<After reset: Undefined>
b Bit Name Function R W
0–15 TIO0CT–TIO9CT 16-bit reload counter value R(Note 1)
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.

TIO9 operation mode select bit 001: Delayed single-shot output mode
010: Continuous output mode
011: PWM output mode
100: Measure clear input mode
101: Measure free-run input mode
110: Noise processing input mode
111: – ditto –
Note: • Operation mode can only be set or changed while the counter is inactive.
