AUTO-RESTART MODE

The Enhanced PWM can be configured to automati-

cally restart the PWM signal once the auto-shutdown

condition has been removed. Auto-restart is enabled by

setting the P1RSEN bit in the PWM1CON register.

If auto-restart is enabled, the CCP1ASE bit will remain

set as long as the auto-shutdown condition is active.

When the auto-shutdown condition is removed, the

CCP1ASE bit will be cleared via hardware and normal

operation will resume.
