19.3.2.15 PWM Shutdown Register (PWMSDN)
The PWMSDN register provides for the shutdown functionality of the PWM module in the emergency
cases. For proper operation, channel 7 must be driven to the active level for a minimum of two bus clocks.

Bit 7
PWM Interrupt Flag — Any change from passive to asserted (active) state or from active to passive state will
be flagged by setting the PWMIF flag = 1. The flag is cleared by writing a logic 1 to it. Writing a 0 has no effect.
0 No change on PWM7IN input.
1 Change on PWM7IN input
PWM Interrupt Enable — If interrupt is enabled an interrupt to the CPU is asserted.
0 PWM interrupt is disabled.
1 PWM interrupt is enabled.
PWM Restart — The PWM can only be restarted if the PWM channel input 7 is de-asserted. After writing a logic
1 to the PWMRSTRT bit (trigger event) the PWM channels start running after the corresponding counter passes
next “counter == 0” phase. Also, if the PWM7ENA bit is reset to 0, the PWM do not start before the counter
passes $00. The bit is always read as “0”.
