Interrupts
Depending on the interrupt mask in the PWM_IMR1 and PWM_IMR2 registers, an interrupt can
be generated at the end of the corresponding channel period (CHIDx in the PWM_ISR1 regis-
ter), after a fault event (FCHIDx in the PWM_ISR1 register), after a comparison match (CMPMx
in the PWM_ISR2 register), after a comparison update (CMPUx in the PWM_ISR2 register) or
according to the transfer mode of the synchronous channels (WRDY, ENDTX, TXBUFE and
UNRE in the PWM_ISR2 register).
If the interrupt is generated by the flags CHIDx or FCHIDx, the interrupt remains active until a
read operation in the PWM_ISR1 register occurs.
If the interrupt is generated by the flags WRDY or UNRE or CMPMx or CMPUx, the interrupt
remains active until a read operation in the PWM_ISR2 register occurs.
A channel interrupt is enabled by setting the corresponding bit in the PWM_IER1 and
PWM_IER2 registers. A channel interrupt is disabled by setting the corresponding bit in the
PWM_IDR1 and PWM_IDR2 registers.
