P1M<1:0>

DC1B<1:0> CCP1M<3:0>
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 P1M<1:0>: Enhanced PWM Output Configuration bits
(1)
Capture mode:
Unused
Compare mode:
Unused
PWM mode:
If CCP1M<3:2> = 00, 01, 10:
xx = P1A assigned as Capture/Compare input; P1B, P1C, P1D assigned as port pins
(1)
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
(1)
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
(1)
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>: ECCP1 Mode Select bits
0000 = Capture/Compare/PWM off (resets ECCP1 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 ECCP1 pin low; set output on compare match (set CCP1IF)
1001 = Compare mode: initialize ECCP1 pin high; clear output on compare match (set CCP1IF)
1010 = Compare mode: generate software interrupt only; ECCP1 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)
PWM mode:
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
1111 = PWM mode: P1A, P1C active-low; P1B, P1D active-low
