For further details, please refer to manual 26/755 “PCD2.H110 - Universal counting

and measuring module”.

Watchdog: This module cannot be used on the base address 240 (or 496 for the

PCD2.M17x), because it would interact with the watchdog, and would cause a

malfunction. For details, please refer to the “Watchdog” section, which describes the

correct use of the watchdog in conjunction with PCD2 components.
