PPG Output Mode Register (PMR)

PMR selects the pulse output mode of the PPG for each group. If inverted output is selected, a
low-level pulse is output when PODRH is 1 and a high-level pulse is output when PODRH is 0. If
non-overlapping operation is selected, PPG updates its output values at compare match A or B of
the TPU that becomes the output trigger. For details, refer to section 12.4.4, Non-Overlapping
Pulse Output.
