For further details, please refer to manual 26/761 “PCD2.H150 - SSI interface for
absolute encoder”.
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.
