PPG Output Mode Register (PMR)

The PMR is an 8-bit readable/writable register that 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 on compare match A or B of the TPU that becomes the output trigger.
For details, refer to section 12.4.5, Non-Overlapping Pulse Output.

Description
Group 3 Inversion
Selects direct output or inverted output for pulse
output group 3.
0: Inverted output
1: Direct output
Group 2 Inversion
Selects direct output or inverted output for pulse
output group 2.
0: Inverted output
1: Direct output
Reserved
Group 3 Non-Overlap
Selects normal or non-overlapping operation for
pulse output group 3.
0: Normal operation (output values updated at
compare match A in the selected TPU channel)
1: Non-overlapping operation (output values at
compare match A or B in the selected TPU
channel)
Group 2 Non-Overlap
Selects normal or non-overlapping operation for
pulse output group 2.
0: Normal operation (output values updated at
compare match A in the selected TPU channel)
1: Non-overlapping operation (output values at
compare match A or B in the selected TPU
channel)
