Section 8 16-Bit Timer
Example of Synchronization: Figure 8.25 shows an example of synchronization. Channels 0, 1,
and 2 are synchronized, and are set to operate in PWM mode. Channel 0 is set for counter clearing
by compare match with GRB0. Channels 1 and 2 are set for synchronous counter clearing. The
timer counters in channels 0, 1, and 2 are synchronously preset, and are synchronously cleared by
compare match with GRB0. A three-phase PWM waveform is output from pins TIOCA
and TIOCA
8.4.4
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 8.4 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.
