triangular PWM waveform is output from the TOTm1 pin.
while it is counting down, an overflow interrupt request signal (INTTTIOVm) is generated.

The 16-bit counter is cleared from FFFFH and 0000H and starts counting when the TTmCE bit is set to 1. The
In the triangular-wave PWM output mode, the counter counts up or down. When the 16-bit counter reaches 0000H
The counting direction is changed from up to down when the value of the 16-bit counter matches that of the CCR0
The PWM waveform can be changed by rewriting the TTmCCRa register during operation. To change the PWM
The cycle of the triangular PWM waveform is set by the TTmCCR0 register and its duty factor is set by the
Even when changing only the cycle of the PWM waveform, first set a period to the TTmCCR0 register, and then
To transfer data from the TTmCCRa register to the CCRa buffer register, the data must be written to the TTmCCR1
