enabled), bits OPOL1 and OPOL0 are 01b (when timer RC pin is pulled up, timer RC output level is fixed to
high impedance during output waveform manipulation period), and the RESTATS bit is 0 (output waveform
manipulation is stopped by software and output is restarted)
OPOL0 are 10b (timer RC output level is fixed low during output waveform manipulation period), and the
RESTATS bit is 1 (automatic output waveform manipulation is stopped by software and automatic output is
restarted)
