PWOCR1
PWOCR2
PWOCR is an 8-bit read/write register that enables or disables PWM output. PWOCR1 controls
outputs PWM1H to PWM1A, and PWOCR2 controls outputs PWM2H to PWM2A.
PWOCR is initialized to H'00 upon reset, and in standby mode, watch mode, subactive mode,
subsleep mode, and module stop mode.
