4 Bytes Signed (2’s cplt) Int 16 (HH-HL) +16 bits fixed point (LH-LL) Volt

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.
