Pulse-Width Modulator (S12PWM8B8CV1)

Interrupts
The PWM module has only one interrupt which is generated at the time of emergency shutdown, if the
corresponding enable bit (PWMIE) is set. This bit is the enable for the interrupt. The interrupt flag PWMIF
is set whenever the input level of the PWM7 channel changes while PWM7ENA = 1 or when PWMENA
is being asserted while the level at PWM7 is active.
In stop mode or wait mode (with the PSWAI bit set), the emergency shutdown feature will drive the PWM
outputs to their shutdown output levels but the PWMIF flag will not be set.
A description of the registers involved and affected due to this interrupt is explained in
Section 13.3.2.15,
“PWM Shutdown Register
(PWMSDN)”.
The PWM block only generates the interrupt and does not service it. The interrupt signal name is PWM
interrupt signal.
