PWM Mode

In PWM mode GRA and GRB are paired and a PWM waveform is output from the TIOCA pin.

GRA specifies the time at which the PWM output changes to 1. GRB specifies the time at which

the PWM output changes to 0. If either GRA or GRB compare match is selected as the counter

clear source, a PWM waveform with a duty cycle from 0% to 100% is output at the TIOCA pin.

PWM mode can be selected in all channels (0 to 2).

Table 9.4 summarizes the PWM output pins and corresponding registers. If the same value is set

in GRA and GRB, the output does not change when compare match occurs.
