General register settings outside the counting range (H'0000 to GRA3)
Waveforms with a duty cycle of 0% or 100% can be output by setting a general register to
a value outside the counting range. When a buffer register is set to a value outside the
counting range, then later restored to a value within the counting range, the counting
direction (up or down) must be the same both times.
Settings can be made in this way by detecting GRA3 compare match or TCNT4 underflow
before writing to the buffer register. They can also be made by using GRA3 compare match
to activate the DMAC.
