bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

u = Bit is unchanged

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Reset

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-6

Unimplemented:

Read as ‘0’

bit 5-4

DC1B<1:0>:

PWM Duty Cycle Least Significant bits

Capture mode:

Unused

Compare mode:

Unused

PWM mode:

These bits are the two LSbs of the PWM duty cycle. The eight MSbs are found in CCPR1L.

bit 3-0

CCP1M<3:0>:

CCP1 Mode Select bits

0000

= Capture/Compare/PWM off (resets CCP1 module)

0001

= Reserved

0010

= Compare mode: toggle output on match

0011

= Reserved

0100

= Capture mode: every falling edge

0101

= Capture mode: every rising edge

0110

= Capture mode: every 4th rising edge

0111

= Capture mode: every 16th rising edge

1000

= Compare mode: initialize CCP1 pin low; set output on compare match (set CCP1IF)

1001

= Compare mode: initialize CCP1 pin high; clear output on compare match (set CCP1IF)

1010

= Compare mode: generate software interrupt only; CCP1 pin reverts to I/O state

1011

= Compare mode: Special Event Trigger (CCP1 resets Timer, sets CCP1IF bit, and starts A/D conversion

if A/D module is enabled)

11xx

= PWM mode
