The Enhanced PWM can be configured to automatically
restart the PWM signal once the auto-shutdown condi-
tion has been removed. Auto-restart is enabled by
If auto-restart is enabled, the ECCPxASE bit will
remain set as long as the auto-shutdown condition is
active. When the auto-shutdown condition is removed,
the ECCPxASE bit will be cleared via hardware and
normal operation will resume.

The module will wait until the next PWM period begins,
however, before re-enabling the output pin. This behav-
ior allows the auto-shutdown with auto-restart features
to be used in applications based on current mode of
PWM control.
