Description:
Voltage value of the 16 inputs pins between -12V and 12V. This value
saturates at ~ -15.5V and 24V.
Notes:
The A/D converter has a 10 bits resolution (~0.43V).
The acquisition is done every 850µs and is asynchronous with the read
access of the A/D VALUE registers. When you access this register, you get
the last A/D conversion result, which can be up to 850µs old.
