In sawtooth wave modulation mode, one cycle of carrier waveform consists of one timer B2 underflow cycle.
A timer Ai one-shot pulse (i = 1, 2, and 4) is generated by using a timer B2 underflow signal as a trigger. Single
one-shot pulse from timer Ai is used to output one cycle of the PWM waveform. Table 16.4 lists specifications and
settings of sawtooth wave modulation mode.
