Legend: x = unknown, u = unchanged, — = unimplemented read as ‘0’. Shaded cells are not used by PWM and Timer2.
Timer Prescaler (1, 4, 16)
PR2 Value
Maximum Resolution (bits)
Set the PWM period by writing to the PR2
register.
Set the PWM duty cycle by writing to the
CCPR1L register and CCP1CON<5:4> bits.
Make the CCP1 pin an output by clearing the
TRISCCP<2> bit.
Set the TMR2 prescale value and enable Timer2
by writing to T2CON.
Configure the CCP1 module for PWM operation.
