So let us try to understand and Typekit.
First, we'll try to include all the many different drivers, so we have an exciting DC dotage that
will be handling all the work related to an injured controller experiment or stage where we will be
finding all the hardware related information.
Select the which consists of an EPA that it used to correctly initialize, as well as enable an exception
handler.
And then for a timer, we have a democracy right now.
If you go through a timer on something interesting to notice, it's compared to GPIO.
We do not have anything as global enable or an interpreter, right?
So you could see we have a self-tests get set set options lookup config.
The API related to BW aim then database to start, then stop a timer.
But we do not have an EPA that could be used to perform a global enable and the enable rate.
So the peripheral specific enable EPAs are not available, which we have in n GPIO peripheral drivers
right to.
In such case, we could ignore that step.
That is, we do not need to perform that step.
So if you remember.
OK, so while we configure our rights so we enable execution, OK, then we enable those switch one,
OK, which will allow us an AI in DC to receive the signal from a benefit.
And then we since we do not have a global enable line and interpretable, we could simply skip the step
and start an operation.
Remember this step whenever you do not Lane Global enable an an interoperable EPA is available in a
driver specific, very, very specific driver.
So in that case, you could ignore that, right?
So let it just go through an entire code.
So to initialize the AI in DC, we have declared an instance structure that basically mean we are utilizing
a initialize metric.
Similarly, when we consider timer, we declare only an instance structure of a timer.
So here also, we will be utilizing the initialize, right?
So will not be using the lookup config and to initially.
So when we go to timer in it.
OK.
What we are doing is we are calling initialize function and this required to think first one is an instance
structure and second one is that device i.e., right?
So this you could find out from the X parameter dog they tried to.
Once you add this to arguments, this will perform an initialization of a timer and then stages of initialization
will be stored in a status variable rate.
Then we are performing various duties as equals to existing success, and if that is the case, will
just be mentioning that timer and it is successful and Daimler need to be right.
So this completes all the code related to initialization of a timer, and we are not configuring a timer
over here as we progress to our mean code.
There we will be performing a different option for a time of great.
Next step is to initialize our own to control the right time configuring an interplanetary A. So we
go ahead and we create a new function, which is INTC in it.
OK, now since we are working predominantly on an instance of just that, here also we called and initialize
API.
OK, where we need to pass an instance structure and the device I'd write again.
The device ID could be found out from X parameter Nottage, and then this will return the status of
an initialization.
So if citizens access to success in that case, we could just mention that INTC and it is successful
and we could mention I and DC need for this makes sense.
So this is the only step that we want to perform for an initialization of an entrapment.
Look, we are not performing self-test.
We're here.
You could perform if you wish to perform a test on an intra controller, right?
Then the step two will be to vertically initialize an exception and enable an exception handler, right?
So this is a three step process.
So first we call an exception in it.
OK, so this will initialize our exception.
Then we need to specify the type of an exception, OK?
And to do that, we have an IED, right?
So they like section ID and is used to recognize an exception from an integer.
And in that case, the master range of handler for us will be and in Japan, which is available in INTC,
right?
And finally, we need to add an argument as an AI in this right, which is an instance structure for
our intraperitoneal.
So once this is done, we will just be performing exception enable, right?
So this will close our switch number.
What right?
So that this we close our switch, we also initialize our interpreter, right?
Remember, note that almost in all the control of this process will remain constant.
So there's three statements won't be changing.
So in the case of GPI, also desired.
Exactly similar, and in the case of or of watchdog timer initiative that will be seeing later on,
this statement will remain as a threat, then we proceed to specify the IED that we get for our time.
OK.
And along with that, what will be the function that will be executed when we have an inch or so to
find an IED or a timer?
We just need to go to an experimental detection look for.
Victor, right, so once we find the D.C. OK?
So here you will see the MRC director.
So this is how we recognize the unique ID for an enterprise, so a diesel for GPO, it was GPO vector
in the case of dmaa.
Curtis, the MRC direct right to.
Once you found out an ID, you just need to add it and then connect it to connect function.
First argument is an intra controller instant structure.
OK, the next one is a unique idea that we get for a tailor.
And then once this interest is recognized, OK by an interpreter, we will tell an interpreter to execute
this function, which is the function that really glad for our interest rates.
And here we are.
Specifying the food argument as an instance, I guess whenever you want to add to the argument for a
callback reference or peripheral with which you are looking just at an instance structure of diet as
an argument, right?
So that is something useful to a year since we are working with an.
So we are adding the time or instance during a call back or if it's right, next step is to enable,
right.
So once we call an animal where we specify an end in trip controller, internal structure and the unique
ID will basically close the switch.
And now we do not have anything as global enabler or entropy enabling end time or driver.
So we will skip that step and will start an operation of an introduction from the right.
And this will again be in real mode.
That is, we will be sensing the interest from the hardware, right?
So for that reason, we have our data flag as real, right?
So this completes all the interpolated configuration.
Then we call this API into our main application rate.
So we are calling time or need.
We are calling AI indices.
So really just understand the function, what we are doing when we have interest rates.
So when we have an interest that basically mean that our timer has expired, so we are just double checking
whether timer is really expired.
So while this function basically returns to a timer expired and not approval before this and will be
coming out of while the timer is not expired, this will be the only threatening default and not of
false will be true.
So we will be waiting in this steep rate.
But since our time is expired, we will be coming out of this way.
Look, and then we just mentioned interest rate.
So as the system we will be utilizing DMA CTO reset to what this will do is this will again initialize
our timer with the value that users set.
And then we are again ready to perform execution of a timer so that we have a multiple interest rate.
Right now, we go ahead and understand the code that we did for the configuration of the timer.
The first thing that we do is to stop an operation of a timer.
Then we are sensing the option that are being saved by default rate.
So to know an option that has been set by default in a timer, we have a good option where we just need
to add the instant structure and the TMC number, right?
So there's also represent the ID for our timer one, which is zero.
Once we have an option, we'll just perform operation of an option by calling an operator.
So here what we want to do is we want to perform the counter operation and down to do that.
We have this low gain to enable and we have this option, right?
So this too will just be free.
Now what this will do is this will enable an intro and second thing it will do is it will allow us to
go in a downward direction.
Right now, we plan to have a delay of two seconds or so to get the delay of two.
Second, we just need to add two into 10 days to it, right?
That is what we are doing over here and we set the reset value rate.
Then we reset timer and we are starting its celebration, right?
And now we wait for an intro.
So we have not utilized the full API that we use when we are discussing any save time.
Right now, we are not waiting for the timer to expire and then we display the timer expiring, but
instead we will just be processing normal code over here.
OK, and as soon as we have an interrupt, we will be serving the goal that we have written in it into
hand, right?
So here we have just waiting for an intro to occur and once into DR.
OK, so this will happen after an interval of two seconds.
We go to this zen handler.
Now we do not have anything as a disable or enable and interrupt in the peripheral specific driver.
We do have and enable and disable controller if you explore AI in D.C., so we do have an API to enable
and disable, right, so.
But what this will do is this will not allow us to sense an interest from sources other than the time,
right?
So that will not be a good idea.
So whenever you are in a situation where you do not find the global enabler or an entropy label in a
timer, see that you do not add anything to drink to just serve and interrupt and then come out of and
interpret, and this will be automatically handled by process.
We do not need to do anything.
We just need to serve and into another important thing that we could do is you could also acknowledge
and interrupt.
That will always be a good strategy so we can just add and acknowledge OK.
And here it requires again the two argument, right?
So the instance structure and the unique idea.
So we'll just be copying it and adding it to it, right?
So we could always use this episode also, but this restricts us from sensing other right and that is
what we do not want.
So whenever you do not play, enable and disable EPA is in and peripheral specific driver like here
we have a marker.
So if you just explore extreme procedure driver, you do not find anything as a global enable or enable
or disable.
In that case, you simply skip this step that we are performing an NGO that is disabling and intrusive,
then performing the respective task, clearing up, ending in trip and then finally enabling a contract.
So you could simply skip that task.
And we will just be doing what you want to do when we have an interest rate, that is what we are doing
over here.
So let me just go ahead and build up an entire application project that once built a successful will
be getting a year left right and now will try to execute our application on to an FPGA right.
So DBA guys launch on hardware.
And then.
We go to our I do still mean, OK, we will connect the widest terminal to concerts to operate at the
board of nine six zero zero, right, and everything that we need to do is to click on this resume button,
right?
So first, I anticipated a successful day in time, whether it is successful and then you could see
at an interval of two seconds, you have an intro been generated by our timer pacing, right?
So this is how you utilize the entropy, then timer.
If you know this is all to give us an understanding what should be your strategy when you do not find
a global enable or a benefit of specific enable?
EPA is their drive rate will consider one more example OK, where we try to use and interpret.
Watchdog timer.
