Figure 16.11
Figure 16.11 shows an example of the triangular wave modulation operation (three-phase mode 0). Figures 16.12
and 16.13 show examples of the triangular wave modulation operation (three-phase mode 1).
INVC1 register = 0
INVC1 register = 1
Timer A4 start trigger signal
Triangular Waveform as a Carrier Wave (Three-phase mode 0)
IR bit in the TB2IC register
Timer A4 one-shot pulse
NOTE:
The above applies under the following conditions:
- INVC0 register: INV01 bit = 0 (ICTB2 counter is incremented by 1 when timer B2 underflows)
- INVC1 register: INV10 bit = 0 (Timer B2 underflow)
- ICTB2 register = 01h (Timer B2 interrupt is generated every timer B2 underflow)
The following shows examples to change PWM output levels.
- Default value of the timer: TA4 = a
- Default value of the registers IDB0 and IDB1: DU0 = 1, DUB0 = 0, DU1 = 0, and DUB1 = 1
They are changed to DU0 = 1, DUB0 = 0, DU1 = 1, and DUB1 = 0 at the sixth timer B2 interrupt.
