selects the convert signal for the acquisition.
Joint_Reset_Register
AI configuration start = 1;
AI_SI2_Load_A_Register
AI SI2 special ticks - 1 = 399;
AI_SI2_Load_B_Register
AI SI2 ordinary ticks -1 = 399;

11. Perform Analog Input Example 1 Step 4.
12. Call
AI_Arming
to arm the analog input counter.
AI_Command_1_Register
AI SC arm = 1;
AI SI arm = 1;
AI SI2 arm = 1;
AI DIV arm = 1;
13. Now start the acquisition with
AI_Start_The_Acquisition
.
AI_Command_2_Register
AI START1 pulse = 1;
14. Poll the AI FIFO not empty flag in the AI_Status_1_Register until not
empty and read the ADC FIFO data in the ADC_FIFO_Data_Register.
Do
{
If (AI FIFO not empty) then
read FIFO data;
} while (80 samples have not been read)
