Synchronized Operation: Figure 10.27 shows an example of synchronized operation. Channels
0, 1, and 2 are set to synchronized operation and PWM output. Channel 0 is set for a counter clear
upon compare match with GRB0. Channels 1 and 2 are set for counter clears by synchronizing
clears. Accordingly, their timers are sync preset, then sync cleared by a GRB0 compare match,
and then a three-phase PWM waveform is output from the TIOCA0, TIOCA1 and TIOCA2 pins.
See section 10.4.4, PWM Mode, for details on the PWM mode.
