7.5.13 Operation as non-complementary modulation output function (type 1)
complementary modulation output function (type 1) can be used to realize this method. The non-complementary
modulation output function sets six duty widths for one period and generates a 6 or 3 PWM output. One period
generation channel and six duty generation channels are prepared (6-phase PWM output function). Channel 0 is used
for generating the cycle and channels 2 to 7 are used for generating the duty (6-phase PWM output function). See

and TLS2 to TLS7 (OPMR registers) are used if inversion control is required.
Modulation output of the PWM output isn’t performed when TROm set to “0”.

Non-complementary modulation output is generated by using PWM, which is generated using the 6-phase PWM
The master channel operates in the interval timer mode and counts the periods.
Slave channel 1 operates in one-count mode and generates a real-time output trigger. To match the real-time
Slave channels 2 to 7 operate in one-count mode, count the duty factor, and generate 6-phase PWM waveforms.
Furthermore, modulation output is controlled by manipulating TMEm. Non-complementary modulation output can
To modulate the PWM and real-time outputs and output them from the TOm pin, operation must be started with the
Modulation control of the PWM and real-time outputs is performed when TROm being “1” (active level: high level).

TS00, TS01, or TSm cannot be set to “1” (forcible restart) while TE00 = 1, TE01 = 1, or TEm = 1. If
TS00, TS01, or TSm is set to “1” while TE00 = 1, TE01 = 1, or TEm = 1, the counter value (TCR00,
TCR01, or TCRm) will be illegal and TOm will not be able to output the expected waveform.
