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.
