Watchdog: This module can interact with the watchdog; if it is used on base
address 240 (or 496 for the PCD2.M17x), the last input with address 255 (or 511
for the PCD2.M17x) cannot be used.
For details, please refer to the
section A4 “Hardware Watchdog”
, which describes
the correct use of the watchdog in conjunction with PCD components.
