REGISTER 14-2: CCPxCON: ENHANCED CCPx CONTROL REGISTER
R/x-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
PxM<1:0> DCxB<1:0> CCPxM<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 PxM<1:0>: Enhanced PWM Output Configuration bits
If CCPxM<3:2> = 00, 01, 10: (Capture/Compare modes)
xx = PxA assigned as Capture/Compare input; PxB, PxC, PxD assigned as port pins
Half-Bridge ECCP Modules
(1)
:
If CCPxM<3:2> = 11: (PWM modes)
0x = Single output; PxA modulated; PxB assigned as port pin
1x = Half-Bridge output; PxA, PxB modulated with dead-band control
Full-Bridge ECCP Modules
(1)
:
If CCPxM<3:2> = 11: (PWM modes)
00 = Single output; PxA modulated; PxB, PxC, PxD assigned as port pins
01 = Full-Bridge output forward; PxD modulated; PxA active; PxB, PxC inactive
10 = Half-Bridge output; PxA, PxB modulated with dead-band control; PxC, PxD assigned as port
pins
11 = Full-Bridge output reverse; PxB modulated; PxC active; PxA, PxD inactive
bit 5-4 DCxB<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 CCPRxL.
Note 1: See Table 14-1 to determine full-bridge and half-bridge ECCPs for the device being used.
