TIO0CT–TIO9CT

16-bit counter value

R(Note 1)

Note 1: Protected against write during PWM output mode.

Note: • These registers 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.
