Notes:
1. Pin 4, 13 and 17 are the same analog reference ground;
2. Pin 1 and 2, 14 and 15 are two pairs of differential analog input. If not using differential signal,
connect pin 1, 2, 4 and 15 separately to analog reference ground (pin 4, 13 and 17), you will
have 4 channels of programmable analog input;
3. Pin 12 and 24 are the same digital signal reference.
