PWM AUTO-SHUTDOWN WITH FIRMWARE RESTART (PRSEN = 0)
8.3.9
AUTO-RESTART MODE
The
Enhanced
PWM
can
be
configured
to
automatically restart the PWM signal once the auto-
shutdown condition has been removed. Auto-restart is
enabled by setting the PRSEN bit in the PWM1CON
register.
If auto-restart is enabled, the ECCPASE bit will remain
set as long as the auto-shutdown condition is active.
When the auto-shutdown condition is removed, the
ECCPASE bit will be cleared via hardware and normal
operation will resume.
