SAM7S Series
Interrupts
Register Mapping
Depending on the interrupt mask in the PWM_IMR register, an interrupt is generated at the end
of the corresponding channel period. The interrupt remains active until a read operation in the
PWM_ISR register occurs.
A channel interrupt is enabled by setting the corresponding bit in the PWM_IER register. A chan-
nel interrupt is disabled by setting the corresponding bit in the PWM_IDR register.
