If timer T2 is configured as an absolute timer and the application modifies
the values in this register while the timer is running, the change becomes
effective immediately and the timer T2 will expire according to the changed
values.
If timer T2 is configured as a relative timer and the application changes the
values in this register while the timer is running, the change becomes
effective when the timer has expired according to the old values.
Timer T2 Macrotick Offset — This field holds the macrotick offset value for timer T2.
Timer T2 Macrotick Low Word — This field defines the low word of the macrotick value for timer T2.
