Perform Analog Input Example 1 Step 4.
9.
Call
AI_Arming
to arm the analog input counter.

10. The function
AI_Start_The_Acquisition
starts the acquisition
process.

AI START1 Pulse = 1;
11. 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 (20 samples have not been read)
Example 3
Example 3 performs the same acquisition as Example 2, but with interrupts.
Acquire 5 scans at a scan interval of 1ms. The scan list contains channels
5, 4, 1, and 0 respectively. The channels are configured as RSE at a gain
of 1. Within each scan, the sample interval should be 100f during the
