Interrupt on basic PWM controller
The basic PWM controller can be programmed to generate interrupts on completion of the
blinking sequence.
a)
b)
Each basic PWM controller has its own bit in interrupt the enable/status registers.
If enabled, completion in any of the PWM controller triggers interrupts. No interrupt
is generated if infinite repetition is set.
