Read: Anytime
Write: Only in test (special) mode; has no effect in normal modes
To ensure coherent reading of the timer counter, such that a timer
rollover does not occur between two back-to-back 8-bit reads, it is
recommended that only half-word (16-bit) accesses be used.
A write to TIMCNT may have an extra cycle on the first count because
the write is not synchronized with the prescaler clock. The write occurs
at least one cycle before the synchronization of the prescaler clock.
