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 (PR4)
register.
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 the CCP1CON<5:4> bits.
For auto-shutdown:
• Disable auto-shutdown; ECCP1ASE = 0
• Configure auto-shutdown source
• Wait for Run condition
For

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