In triangular wave modulation mode, one cycle of carrier waveform consists of two timer B2 underflow cycles.
A timer Ai one-shot pulse (i = 1, 2, and 4) is generated by using a timer B2 underflow signal as a trigger. Two of
the timer Ai one-shot pulses are used to output one cycle of the PWM waveform. Table 16.3 lists specifications and
settings of triangular wave modulation mode.
Triangular wave modulation mode has two operation modes, three-phase mode 0 and three-phase mode 1.
TAi register is used in three-phase mode 0. Every time a timer B2 underflow interrupt occurs, the one-shot pulse
width is set in the TAi register.
Registers TAi and TAi1 are used in three-phase mode 1. Two different widths of the one-shot pulse can be set in
these registers. If a setting value of the ICTB2 register is n, a timer B2 underflow interrupt is generated every n-th
or every 2n-th timer B2 underflow to set values in registers TAi and TAi1.
: Value set to the TAi1 register at k-th time.
: Value set to the TAi register at k-th time.
: Value set to the TAi register at even-numbered time.
: Value set to the TAi register at odd-numbered time.

Timer B2 underflow
When a value is written to the IDBp register (p = 0, 1), the value is transferred only once by the
first transfer trigger.
• At the falling edge of the one-shot pulse of timer A1, A2 and A4 (INV16 = 0)
• At the rising edge of the three-phase output shift register (INV16 = 1)
