CHAPTER 6 PROGRAMMABLE PULSE GENERATOR (PPG) TIMER
Using an interrupt by borrow, set the PGMS (mask bit)
to "1". If the PGMS (mask bit) is set to "0" during use
of an interrupt by borrow, the PWM waveform can be
output without generating glitches.
Using an interrupt by compare match, write to the
duty setting register the same values as that in the
cycle setting register.
