Digital outputs set up as PPM's PPM0-7

Each has an offset & duty

Digital inputs 0-11 IN0-11

Digital outputs 0-7 OUT0-7

2 x PWM and 2 x PPM channels (PPM0-1 offset + duty)

8 PWM channels on pins OUT0-7

The 8 unipolar channels voltage ~ -2.039 V
The channel pairs vary voltage ~ -0.005 V (depends n gain)
The 4 mA channels vary current ~ 0.154 mA
