16-bit counter value
W= : Whether writing to the counter is enabled or disabled depends on a combination of timers and timer
operation modes.
For details, see (1) TOM timer counter write enable/disable conditions.
Note: This register must always be accessed in halfwords.
The TOM0 Counter is a 16-bit down-counter. After the timer is enabled (by writing to the enable bit
in software or by TID2 underflow/overflow signal), it starts counting synchronously with the count
clock. During PWM output and single-shot PWM output modes, this counter is disabled against
write.
