Functional Description
The counter period of a running timer can be modified, by first disabling the timer,
setting a new load value and then enabling the timer again (see the following figure).
It is also possible to change the counter period without restarting the timer by writing the
LDVAL register with the new load value. This value will then be loaded after the next
trigger event (see the following figure).

37.4.1.2 Debug Mode
In debug mode, the timers will be frozen based on FRZ bit in PIT module control
register. This is intended to aid software development, allowing the developer to halt the
processor, investigate the current state of the system (for example, the timer values) and
then continue the operation.
