Note 1: Protected against write during PWM output mode.
Note: • This register must always be accessed in halfwords.
The TIO counters are a 16-bit down-counter. After the timer is enabled (by writing to the enable bit in software or
by external input), the counter starts counting synchronously with the count clock.
These counters are protected against write during PWM output mode.
