— — DC2B1 DC2B0 CCP2M3 CCP2M2 CCP2M1 CCP2M0
bit 7 bit 0
bit 7-6 Unimplemented: Read as ‘0’
bit 5-4 DC2B1:DC2B0: PWM Duty Cycle bit 1 and bit 0
Capture mode:
Unused.
Compare mode:
Unused.
PWM mode:
These bits are the two LSbs of the 10-bit PWM duty cycle. The eight MSbs of the duty cycle are
found in CCPR2L.
bit 3-0 CCP2M3:CCP2M0: CCP2 Mode Select bits
0000 = Capture/Compare/PWM off (resets CCP2 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 CCP pin low, on compare match force CCP pin high
1001 = Compare mode, initialize CCP pin high, on compare match force CCP pin low
1010 = Compare mode, generate software interrupt only, CCP pin is unaffected
1011 = Compare mode, trigger special event, resets TMR1 or TMR3 and starts A/D conversion
if A/D module is enabled
11xx = PWM mode
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
