NOTE:
1. When this bit is used in delayed trigger mode 0, set the same count source to the timer B0 and timer B1.

NOTES:
1. Write to this register after setting the PRC1 bit in the PRCR register to 1 (write enabled).
2. If the INV11 bit is 0 (three-phase mode 0) or the INV06 bit is 1 (triangular wave modulation mode), set this bit to 0 (timer
B2 underflow).
3. When setting the IVPCR1 bit to 1 (three-phase output forcible cutoff by SD pin input enabled), Set the PD8
5 bit to 0 (= input
mode).
4. Related pins are U(P8
0), U(P81), V(P72), V(P73), W(P74), W(P75). When a high-level ("H") signal is applied to the SD pin
and set the IVPCR1 bit to 0 after forcible cutoff, pins U, U, V, V, W, and W are exit from the high-impedance state. If a low-
level (“L”) signal is applied to the SD pin, three-phase motor control timer output will be disabled (INV03=0). At this time,
when the IVPCR1 bit is 0, pins U, U, V, V, W, and W become programmable I/O ports. When the IVPCR1 bit is set to 1,
pins U, U, V, V, W, and W are placed in a high-impedance state regardless of which function of those pins is used.
5. When this bit is used in delayed trigger mode 0, set bits TB0EN and TB1EN to 1 (A/D trigger mode).
6. When setting the TB2SEL bit to 1 (underflow of TB2 interrupt generation frequency setting counter[ICTB2]), set the INV02
bit to 1 (three-phase motor control timer function).
