triangular wave PWM output function uses slave channels 2 and 3, slave channels 4 and 5, and slave channels 6 and
7 in combination. The output operations of TOp and TOq are explained next.

The 6 triangular wave modulation PWM output function uses seven channels in combination to output a 6-phase
The 6-phase triangular wave PWM output function is an extension of the function described in 7.5.5 Operation as
It outputs 6 triangular wave modulation PWM from slave channel 2, slave channel 3, slave channel 4, slave
The output pulse period, positive-phase active width, and reverse-phase active width can be calculated by the
Errors will be included in the output waveforms when the dead time function is used. The output width of a
The master channel operates in the interval timer mode and counts the periods.
A carrier period is generated in two periods of the master channel count.
The count operation of the slave channel is controlled by defining the first period of the master channel as a down
TO00 of the master channel outputs up and down statuses.
TO00 of the TO0 register must be manipulated while TOE00 of the TOE0 register is 0 and the default level must be
TO00 of the TO0 register is set to 1 when MD000 of the TMR0 register is 0, and TO00 is set to 0 when MD000 is 1.
By setting the default level, a high level is output from TO00 during a down status and a low level is output during
Slave channel 1 is not used as a 6-phase PWM output function.
(To use the modulation output function, slave channel 1 is used as the real-time output trigger generation channel.
Dead time is controlled by using slave channels 2, 4, 6 and slave channels 3, 5, 7 in combination. The 6-phase
