The above applies to INVC0 = 00XX11XXb (X varies depending on each system) and INVC1 = 010XXXX0b.
The PWM output may vary as follows:
Case 2: When INV11 = 0 (three-phase mode 0)

-INV01 = 0 and ICTB2 = 2h (timer B2 interrupt generated every 2nd time the timer B2 underflows), or INV01 = 1,
-The setting of registers TA4 and TA41 are varied every time a timer B2 interrupt is generated,
-Default value of registers IDB0 and IDB1: DU0 = 1, DUB0 = 0, DU1 = 0, DUB1 = 1
-INV01 = 0 and ICTB2 = 1h (timer B2 interrupt generated every time timer B2 underflows)
-TA4 register setting is varied every time a timer B2 interrupt is generated,
-Default value of registers IDB0 and IDB1: DU0 = 1, DUB0 = 0, DU1 = 0, DUB1 = 1
INV00 = 1, and ICTB2 = 1h (timer B2 interrupt generated every time the timer B2 underflows when the reload
control signal for timer A1 is set to 1)
Default value: TA41 = a’, TA4 = a
On the first timer B2 interrupt: TA41 = b’, TA4 = b; the second time: TA41 = c’, TA4 = c
On the third time: DU0 = 1, DUB0 = 0, DU1 = 1, DUB1 = 0
Default value: TA4 = a’
On the first timer B2 interrupt: TA4 = a; 2nd time: TA4 = b’; 3rd time: TA4 = b; 4th time: TA4 = c’; 5th time: TA4 = c
On the sixth time: DU0 = 1, DUB0 = 0, DU1 = 1, DUB1 = 0
