9.4.5
During wait mode, the operation of the motor controller pins are selectable between the following two
options:
9.4.6
All module clocks are stopped and the associated port pins are set to their inactive state, which is defined
by the state of the RECIRC bit. The motor controller module registers stay the same as they were prior to
entering stop or pseudo-stop modes. Therefore, after exiting from stop or pseudo-stop modes, the
associated port pins will resume to the same functionality they had prior to entering stop or pseudo-stop
modes.
9.5
The motor controller is reset by system reset. All associated ports are released, all registers of the motor
controller module will switch to their reset state as defined in
9.6
The motor controller has one interrupt source.
9.6.1
An interrupt will be requested when the MCTOIE bit in the motor controller control register 1 is set and
the running PWM frame is finished. The interrupt is cleared by either setting the MCTOIE bit to 0 or to
write a 1 to the MCTOIF bit in the motor controller control register 0.
