During debugging (while in Monitor Mode) and the debug-suspend functionality is
enabled (MMCR2.DSUSP = 1, default), timers in certain modules in XC864 can be
suspended based on the settings of their corresponding module suspend bits in the
register MODSUSP. When suspended, only the timer stops counting as the counter
input clock is gated off. The module is still clocked so that module registers are
accessible.

This feature could be quite useful, especially regarding the Watchdog Timer: it allows to
prevent XC864 from unintentional WDT-resets while the user software is not executed
and respectively - not able to service the Watchdog.
