RW
Transfer trigger is generated when the INV07 bit
is set to 1. Trigger to the dead time timer is also
generated when setting the INV06 bit to 1. Read
RW
as 0.
Set the INVC0 register after the PRC1 bit in the PRCR register is set to 1 (write enabled). Rewrite bits
INV00 to INV02, INV04, and INV06 when timers A1, A2, A4, and B2 are stopped.
INV01-INV00 (ICTB Count Condition Select Bit) (b1-b0)
Bits INV00 and INV01 are enabled only when the INV11 bit is set to 1 (three-phase mode 1).
To set the INV01 bit to 1, set the value of the ICTB2 register first, and then set the INV01 bit to 1. Set
the TAIS bit in the TABSR register (timer A1 count start flag) to 1 prior to the first timer B2 underflow.
When the INV11 bit is 0 (three-phase mode 0), the timer B2 underflow is counted regardless of the
values of bits INV01 and INV00.
INV02 (Three-Phase Motor Control Timer Function Enable Bit) (b2)
Set the INV02 bit to 1 to operate the dead time timer, U-, V- and, W-phase output control circuits and
ICTB2 counter.
