1 00:00:00,240 --> 00:00:08,460 In this lesson we shall see how to configure the SS I or SBA module on the TVC lunch by board so to 2 00:00:08,490 --> 00:00:15,450 enable and use any of the pair form modules we must enable the clock to it which SSA will use the RC 3 00:00:15,490 --> 00:00:20,690 GC SSA register to enable the clock to the SSA modules. 4 00:00:20,790 --> 00:00:29,920 Notice that the RC GC SSI is part of the S why as CTO or system controller registers. 5 00:00:30,340 --> 00:00:39,200 A right and a one to either R as you are 1 or 2 are 3 enables the corresponding SSI module. 6 00:00:39,480 --> 00:00:46,510 So if we want to use SSI or SBA one you simply need to write one at our zeros position. 7 00:00:46,510 --> 00:00:54,380 If when I use I mean if I want to use yet SSI 0 we write one at our receivers position. 8 00:00:54,390 --> 00:01:03,900 If when I use SSI or SBA one right one at our Y's position and if we want to use all for SSI modules 9 00:01:03,930 --> 00:01:18,400 we can write 0 0 F to the RC GC SSI register and what 0 extra f gives us is 1 1 is 1 1 1 in 1 over here. 10 00:01:18,550 --> 00:01:25,690 The next register is the SSI control register 0 over here I'm showing the function of each bit in the 11 00:01:25,690 --> 00:01:33,940 register although the conventional SBI uses 8 bit data the SSI modules allow transfer of data between 12 00:01:33,940 --> 00:01:35,260 4 bits to 16. 13 00:01:35,280 --> 00:01:41,050 But please take a look at this table post the video and spend some time observing it. 14 00:01:41,350 --> 00:01:48,040 And since you are so familiar with navigating the data sheet now you can go to the data sheet and find 15 00:01:48,040 --> 00:01:49,300 these registers. 16 00:01:49,310 --> 00:01:50,710 Read more about them. 17 00:01:50,740 --> 00:01:56,260 The purpose of this course was to get you familiar with navigating the data sheet so that you become 18 00:01:56,890 --> 00:02:03,500 an independent self-reliant and proficient and better to develop the next register. 19 00:02:03,520 --> 00:02:12,350 Is the SSI pre-schooler register the lower a bit of the SS ICP s r register are used to divide the CPI 20 00:02:12,370 --> 00:02:19,840 clock before it is fed to the bitrate circuit only if even numbers can be used for the pre-school lessons 21 00:02:19,840 --> 00:02:28,330 that d you must always be 0 for a preschooler registered the lowest value is 2 and the highest value 22 00:02:28,360 --> 00:02:36,490 is two hundred and fifty for the SS AI module in the USC tube can be either master or slave. 23 00:02:36,490 --> 00:02:44,860 We must use the M as bit in the SS AI control register one which is written here as SS I see r one we 24 00:02:44,860 --> 00:02:52,540 must use the M S bit over here to designate the TVC chip as a master or slave and other important bits 25 00:02:52,600 --> 00:03:00,880 in the SS I see R1 one register that is the Enable Disable bit we must use this to disable the module 26 00:03:01,450 --> 00:03:09,010 during initialization process and sort of enable it after the initialization process to enable disable 27 00:03:09,010 --> 00:03:13,990 bits as bits one over here routine here as SS E. 28 00:03:13,990 --> 00:03:21,160 Now let's take a look at the SS AI data register written here as SS Ida R. 29 00:03:21,730 --> 00:03:30,520 The data is placed in the SS Ida R for transmission the SS I.D. R is also used for the received data 30 00:03:30,550 --> 00:03:32,270 buffer in 8 bits. 31 00:03:32,270 --> 00:03:39,850 Data say selection we must place the data into the lower 8 bits of the register in the rest and the 32 00:03:39,850 --> 00:03:43,990 rest of the register is not used in the receive mode. 33 00:03:44,050 --> 00:03:50,080 The data is right justified in the lower 8 bit holds their received data. 34 00:03:52,990 --> 00:04:02,020 This table over here show says the the various SS AI pins we have on our Texas Instruments TVC board 35 00:04:02,440 --> 00:04:05,960 please post the video to take a look at this. 36 00:04:06,070 --> 00:04:15,370 This this image or this table here over here we know where to find SS I 0 pins as well as SSI 1 SSI 37 00:04:15,390 --> 00:04:17,320 2 and SSA 3. 38 00:04:17,320 --> 00:04:23,640 We're going to refer to this table in order to connect our slave device to our microcontroller. 39 00:04:23,770 --> 00:04:28,600 So this the end of this lesson if you have any questions just leave in the questions area and actually 40 00:04:28,600 --> 00:04:29,710 see you in the next lesson.
