The rising edge of each OUT signal functions as a trigger and
activates the 16-bit dead timer.
If PPG output is disabled, "H" will be output until the 16-bit
dead timer stops.
If PPG output is enabled, PPG pulse will be output until the
16-bit dead timer stops.

These bits are used to select the operation mode for the waveform generator.

If the TMD5 to TMD3: bit18 to bit16 are "000
B
", the compare output 2 and 3 signals of the output
compare will be output from RTO2 and RTO3 respectively. The 16-bit dead timer can also be used as a
reload timer.
⋅
If the TMD5 to TMD3: bit18 to bit16 are "001
B
", the compare output 2 and 3 signals of the output
compare will be output from RTO2 and RTO3 respectively when PPG output is disabled
(PGEN2:bit28=0, PGEN3:bit29=0 of the PPG output control register (PICS0)). When PPG output is
enabled (PGEN2:bit28=1, PGEN3:bit29=1 of PPG output control register (PICS0)), PPG pulse will be
output from RTO2 and RTO3 respectively while the compare output 2 and 3 signals of the output
compare are "H". The 16-bit dead timer can also be used as a reload timer.
⋅
The rising edge of each OUT signal functions as a trigger and activates the 16-bit dead timer when
TMD5 to TMD3: bit18 to bit16 are "010
B
". If PPG output is disabled, "H" will be output until the 16-bit
dead timer stops. If PPG output is enabled, PPG pulse will be output until the 16-bit dead timer stops.
(Timer mode)
⋅
When TMD5 to TMD3: bit18 to bit16 are "100
B
", non-overlap signal will be generated at the OUT
signal. (Dead time timer mode)
Note:
To operate the waveform generator in the dead time timer mode, be sure to select the 2-channel mode
(compare control register (OCS23); CMOD: bit28=1) for the compare output 3 of the output compare.
