Chapter 8 Pulse-Width Modulator (S12PWM8B8CV1)

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 8.3.2.15,

“PWM Shutdown Register

The PWM block only generates the interrupt and does not service it. The interrupt signal name is PWM

interrupt signal.
