bit 7
bit 7-6
bit 5-4
Unimplemented:
Read as '0'
CCPxX:CCPxY:
PWM 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 CCPRxL.
bit 3-0
CCPxM3:CCPxM0:
CCPx Mode Select bits
0000
= Capture/Compare/PWM disabled (resets CCPx module)
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, set output on match (CCPxIF bit is set)
1001
= Compare mode, clear output on match (CCPxIF bit is set)
1010
= Compare mode, generate software interrupt on match (CCPxIF bit is set, CCPx pin is
unaffected)
1011
= Compare mode, trigger special event (CCPxIF bit is set, CCPx pin is unaffected);
CCP1 resets TMR1; CCP2 resets TMR1 and starts an A/D conversion (if A/D module
is enabled)
11xx
= PWM mode
Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
’1’ = Bit is set
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared
x = Bit is unknown
