Configure the PWM pins, P1A and P1B (and
P1C and P1D, if used), as inputs by setting the
corresponding TRIS bits.
Set the PWM period by loading the PR2 register.
If auto-shutdown is required do the following:
• Disable auto-shutdown (ECCP1AS = 0)
• Configure source (FLT0, Comparator 1 or
• Wait for non-shutdown condition
Configure the ECCP1 module for the desired
PWM mode and configuration by loading the
CCP1CON register with the appropriate values:
• Select one of the available output
• Select the polarities of the PWM output
Set the PWM duty cycle by loading the CCPR1L
register and CCP1CON<5:4> bits.
For
dead-band delay by loading ECCP1DEL<6:0>
with the appropriate value.
If auto-shutdown operation is required, load the
ECCP1AS register:
• Select the auto-shutdown sources using the

Both Power-on Reset and subsequent Resets will force
all ports to Input mode and the CCP registers to their
Reset states.
This forces the Enhanced CCP module to reset to a
state compatible with the standard CCP module.
If auto-restart operation is required, set the
P1RSEN bit (ECCP1DEL<7>).
