Figure 14.9 Triangular Wave Modulation Operation
The three-phase motor control timer function is enabled by setting the INV02 bit in the INVC0 register to 1.
When this function is selected, timer B2 is used to control the carrier wave, and timers A4, A1, and A2 are
used to control three-phase PWM outputs (U, U, V, V, W, and W). The dead time is controlled by a
dedicated dead-time timer. Figure 14.9 shows an Example of Triangular Wave Modulation Opertation and
Figure 14.10 shows an Example of Sawtooth Wave Modulation Operation.
NOTES:
Triangular waveform as a carrier wave
INV14 = 1
("H" active)
INV00, INV01: Bits in the INVC0 register
INV11, INV14: Bits in the INVC1 register
The above applies to INVC0 = 00XX11XXb and INVC1 = 010XXXX0b (X varies depending on each system.)
INV14 = 0

- Default value of the timer: TA41=m, TA4=m
- Default value of registers IDB0 and IDB1
generated with every second timer B2 underflow) or
INV01= 1, INV00=1 and ICTB2=1h (The timer B2 interrupt is
generated on the falling edge of the timer A reload control
signal)
Registers TA4 and TA41 are changed whenever the
timer B2 interrupt is generated.
They are changed to DU0=1, DUB0=0, DU1=1, DUB1=0
by the third timer B2 interrupt.
