PWMU0 Counter Overtaking Flag
Set by hardware when the counter is higher or equal to SW0F’s value. CF flags an
interrupt if bit W0ECOF is set. W0COF can be set either by hardware or software
but can only be cleared by software.
PWMU0 Module 2 Toggle flag
Set by hardware when a match occurs. Can also be set by software. Must be
cleared by software.
PWMU0 Module 1 Toggle flag
Set by hardware when a match occurs. Can also be set by software. Must be
cleared by software.
PWMU0 Module 0 Toggle flag
Set by hardware when a match occurs. Can also be set by software. Must be
cleared by software.
PWMU0 Counter Overtaking flag
Set to Enable IT on PWMU0 Counter Overtaking Flag.
PWMU0 Module 2 Counter flag
Set to enable IT on PWMU0 Module 2 Toggle flag.
PWMU0 Module 1 Counter flag
Set to enable IT on PWMU0 Module 1Toggle flag.
PWMU0 Module 0 Counter flag
Set to enable IT on PWMU0 Module 0Toggle flag.
