an up status.
The triangular wave modulation PWM output function with dead time uses four channels of channels 0 to 3 or
It outputs riangular wave modulation PWM with dead times from slave channels 2 and 3, and slave channels 6 and
The output pulse cycle, positive-phase active width, and reverse-phase active width can be calculated by using the
Errors will be included in the output waveforms when the dead time function is used. The output width of a
At the master channel, channels 0 and 4 are used.
TCRn operates as a down counter in the interval timer mode.
TCRn loads the value of TDRn at the first count clock, after the channel start trigger bit (TSn) is set to 1.
Afterward, TCRn counts down along with the count clock.
When TCRn has become 0000H, INTTMn is output and TOn is toggled upon the next count clock. TCRn loads the
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
TOn of the master channel outputs up and down statuses.
TOn of the TO0 register must be manipulated while TOEn of the TOE0 register is 0 and the default level must be
TOn of the TO0 register is set to 1 when MDn0 of the TMRn register is 0, and TOn is set to 0 when MDn0 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
Remark n = 00, 04
Pulse period (down/up) = {Set value of TDRn (master) + 1} × 2 × Count clock period
positive-phase active width = {{{Set value of TDRn (master) + 1} − {Set value of TDRp (slave p) }} × 2 −
{Set value of TDRq (slave q) + 1}} × Count clock period
reverse-phase active width = {{{Set value of TDRn (master) + 1} − {Set value of TDRp (slave p) }} × 2 +
{Set value of TDRq (slave q) + 1}} × Count clock period
0% output: Set value of TDRp (slave p) ≥ Set value of TDRn (master) + 1
100% output: Set value of TDRp (slave p) = 0000H
