RECIRC
Recirculation in (Dual) Full H-Bridge Mode
(refer to
Section 16.4.1.3.3, “RECIRC Bit”
)— RECIRC only
affects the outputs in (dual) full H-bridge modes. In half H-bridge mode, the PWM output is always active low.
RECIRC = 1 will also invert the effect of the S bits (refer to
Section 16.4.1.3.2, “Sign Bit (S)”
) in (dual) full H-
bridge modes. RECIRC must be changed only while no PWM channel is operating in (dual) full H-bridge
mode; otherwise, erroneous output pattern may occur.
0 Recirculation on the high side transistors. Active state for PWM output is logic low, the static channel will output
logic high.
1 Recirculation on the low side transistors. Active state for PWM output is logic high, the static channel will
output logic low.

MCTOIE
Motor Controller Timer Counter Overflow Interrupt Enable
0 Interrupt disabled.
1 Interrupt enabled. An interrupt will be generated when the motor controller timer counter overflow interrupt flag
(MCTOIF) is set.
