Module: ECCP (Compare Mode)
The CCP1 output latch, observed on RB3/CCP1/
P1A, can change unexpectedly when the ECCP
module is changed from a set output on match
(CCP1CON<3:0> = “1000”) to clear output on
match (CCP1CON<3:0> = “1001”) or vice versa.
This condition will occur, following an ECCP
Reset, at the third iteration of the following
sequence:
1.
2.
Step 1 of the third iteration will cause the CCP1
output latch to immediately, and erroneously,
change to the inverse of the CCPR1<0> bit. This
gives the appearance of an inverted ECCP
response to the third, and subsequent, compare
match events.
CCPR1<3:0> is changed from “1001” to
“1000” or vice versa.
The TMR1H:TMR1L register pair matches
the CCP1R1H:CCPR1L register pair.

The apparent inverted response will persist until
the CCP1CON<3> bit is cleared (exiting Compare
mode). Interrupts always occur correctly on the
match condition. The error is only in the state of the
CCP1 output latch.
Work around
Option 1
Use the ECCP toggle output on compare match
mode (CCP1CON<3:0> = “0010”).
Option 2
Do not selectively change the CCP1CON<0> bit.
Instead, perform the following:
• Set the RB3 data latch to the same state as
• Next, clear the CCP1CON register (clrf
• Finally, set the CCP1CON<3:0> bits to the
the CCP1 output latch (movf PORTB, f) to
avoid an output glitch when the CCP1CON
register is cleared.
