triangular wave PWM output function with dead time uses master channel 0, slave channel 2, and slave channel 3,

it occurs within the carrier cycle period cannot be specified (0 to 3 times).

setting TOLp and TOLq. When TOLp or TOLq is set to 0, a positive-phase waveform to which dead time has been
added on the positive logic side of the PWM duty is output. When TOLp or TOLq is set to 1, a reverse-phase

TOLp = 0, and TOLq = 0 when TOLp = 1).

Slave channels 1 and 5 are not used as PWM output functions with dead times.
Dead time is controlled by using slave channel p (p = 2, 6) and slave channel q (q = 3, 7) in combination. The
TCRp of slave channel p operates in the up and down count mode, and counts the duty. TCRp loads the value of
TCRp loads the value of TDRp again when INTTMn is generated in an up status of the master channel. Similar
TCRq of slave channels 3, 7 operates in the one-count mode, and counts the dead time.
TCRq loads the value of TDRq and counts down by using count start timing and INTTMp of slave channels 2, 6 as

The set condition of TOq (TOLq = 1) is the generation of INTTMp while the TCRp register counts down. The reset
If the set conditions and reset conditions of TOp and TOq conflict, the set conditions take precedence.
The PWM waveform with dead time can be switched between positive and negative phases for slave channels 2, 6
Cautions 1. TDRn of master channel n must be rewritten during an up status period of slave channels 2, 6
It is also possible to specify whether to add dead time to the positive logic output or the inverted logic output by

(The count status is judged by CSF (TSRp register) of the slave channel or the TOn output
level of the master channel). When the value of TDRn is rewritten during a down status
period, the periods of the down status and up status differ and an expected waveform cannot
be output, because the value of TDRn of the rewritten master channel becomes valid at the
next period.
TSn, TSp, or TSq is set to “1” while TEn = 1, TEp = 1, or TEq = 1, the counter value (TCRn,
TCRp, or TCRq) will be illegal and TOn, TOp, or TOq will not be able to output the expected
waveform.
