1. Set the INVC0 register after the PRC1 bit in the PRCR register is set to "1" (write enable).
2. Set the INV01 bit to "1" after setting the ICTB2 register.
3. The INV01 and INV00 bit settings are enabled only when the INV11 bit in the INVC1 register is set to "1"
4. Set the INV02 bit to "1" to operate the dead time timer, U-, V-and W-phase output control circuits and ICTB2
5. Set pins after the INV02 bit is set to "1". See Table 16.2 for pin settings.

underflows, regardless of INV01 and INV00bit settings, when the INV11 bit is set to "0" (three-phase mode).
When the INV00 bit is set to "1", the first interrupt is generated when the timer B2 counter underflows n-1
times, if n is the value set in the ICTB2 counter. Subsequent interrupts are generated every n times the
timer B2 counter underflows.
