Legend:
R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7-6

P1M<1:0>: PWM Output Configuration bits
If CCP1M<3:2> = 00, 01, 10:
xx = P1A assigned as Capture/Compare input; P1B, P1C, P1D assigned as port pins
If CCP1M<3:2> = 11:
00 = Single output; P1A modulated; P1B, P1C, P1D assigned as port pins

01 = Full-Bridge output forward; P1D modulated; P1A active; P1B, P1C inactive

10 = Half-Bridge output; P1A, P1B modulated with dead-band control; P1C, P1D assigned as port pins

11 = Full-Bridge output reverse; P1B modulated; P1C active; P1A, P1D inactive

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.

CCP1M<3:0>: ECCP Mode Select bits
0000 = Capture/Compare/PWM off (resets ECCP module)

0001 = Unused (reserved)

0010 = Compare mode, toggle output on match (CCP1IF bit is set)

0011 = Unused (reserved)

0100 = Capture mode, every falling edge

0101 = Capture mode, every rising edge

1001 = Compare mode, clear output on match (CCP1IF bit is set)

1010 = Compare mode, generate software interrupt on match (CCP1IF bit is set, CCP1 pin is

unaffected)

1011 = Compare mode, trigger special event (CCP1IF bit is set; CCP1 resets TMR1 or TMR2

1100 = PWM mode; P1A, P1C active-high; P1B, P1D active-high

1101 = PWM mode; P1A, P1C active-high; P1B, P1D active-low

1110 = PWM mode; P1A, P1C active-low; P1B, P1D active-high
