CCPxCON: CCPx CONTROL REGISTER

R/W-00

R/W-0/0

PxM<1:0>(1)

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(1)

Capture mode:

Unused

Compare mode:

Unused

If CCPxM<3:2> = 00, 01, 10:

xx = PxA assigned as Capture/Compare input; PxB, PxC, PxD assigned as port pins

If CCPxM<3:2> = 11:

11 =

Full-Bridge output reverse; PxB modulated; PxC active; PxA, PxD inactive

10 =

Half-Bridge output; PxA, PxB modulated with dead-band control; PxC, PxD assigned as port pins

01 =

Full-Bridge output forward; PxD modulated; PxA active; PxB, PxC inactive

00 =

Single output; PxA modulated; PxB, PxC, PxD assigned as port pins

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.

bit 3-0

CCPxM<3:0>: ECCPx Mode Select bits

1011 = Compare mode: Special Event Trigger (ECCPx resets Timer, sets CCPxIF bit, starts A/D conversion if

A/D module is enabled)(1)

1010 = Compare mode: generate software interrupt only; ECCPx pin reverts to I/O state

1001 = Compare mode: initialize ECCPx pin high; clear output on compare match (set CCPxIF)

1000 = Compare mode: initialize ECCPx pin low; set output on compare match (set CCPxIF)

0111 = Capture mode: every 16th rising edge

0110 = Capture mode: every 4th rising edge

0101 = Capture mode: every rising edge

0100 = Capture mode: every falling edge

0011 = Reserved

0010 = Compare mode: toggle output on match

0001 = Reserved

0000 = Capture/Compare/PWM off (resets ECCPx module)

CCP4/CCP5 only:

11xx =PWM mode

ECCP1/ECCP2/ECCP3 only:

1111 = PWM mode: PxA, PxC active-low; PxB, PxD active-low

1110 = PWM mode: PxA, PxC active-low; PxB, PxD active-high

1101 = PWM mode: PxA, PxC active-high; PxB, PxD active-low

1100 = PWM mode: PxA, PxC active-high; PxB, PxD active-high

Note 1:

These bits are not implemented on CCP<5:4>.
