Triangular Waveform as a Carrier Wave (Three-phase mode 1: INV0 and INV00 = 11b)
INV13 bit in the INVC1 register
INVC1 register = 0
INVC1 register = 1
Timer A4 start trigger signal
NOTE:
The above applies under the following conditions:
- INVC0 register: Bits INV01 and INV00 = 11b (ICTB2 counter is incremented by 1 at the falling edge of the timer A1 reload control signal)
- INVC1 register: INV10 bit = 0 (Timer B2 underflow)
- ICTB2 register = 01h (Every second timer B2 underflow.)
The following shows examples to change PWM output levels.
- Default value of the timer: TA41 = b
First time TA41 = b
- 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 third timer B2 interrupt.
