7.4 CCP1 Module and PORTB Operation

When the CCP module is disabled, PORTB<3> oper-

ates as a normal I/O pin. When the CCP module is

enabled, PORTB<3> operation is affected. Multiplex-

ing details of the CCP1 module are shown on

PORTB<3>, refer to Figure 3.6.

Table 7-5 below shows the effects of the CCP module

.

The CCP1 module will capture an event

on the RB3/CCP1 pin which is driven by

an external circuit. The DCCP bit can

read the signal on the RB3/CCP1 pin.

The CCP1 module will capture an event

on the RB3/CCP1 pin which is driven by

the DCCP bit. The DCCP bit can read

the signal on the RB3/CCP1 pin.

The CCP1 module produces an output

on the RB3/CCP1 pin when a compare

event occurs. The DCCP bit can read

the signal on the RB3/CCP1 pin.

The CCP1 module produces the PWM

signal on the RB3/CCP1 pin. The DCCP

bit can read the signal on the RB3/CCP1

pin.

PORTB<3> functions as normal I/O.

PORTB<3> always reads 0 when config-

ured as input. If PORTB<3> is config-

ured as output, reading PORTB<3> will

read the data latch. Writing to

PORTB<3> will always store the result in

the data latch, but it does not drive the

RB3/CCP1 pin.
