TABLE 14-2: INTERACTIONS BETWEEN CCP1 AND CCP2 FOR TIMER RESOURCES

CCP1 Mode CCP2 Mode Interaction

Capture Capture Each module can use TMR1 or TMR3 as the time base. The time base can be different

for each CCP.

Capture Compare CCP2 can be configured for the Special Event Trigger to reset TMR1 or TMR3

(depending upon which time base is used). Automatic A/D conversions on trigger event

can also be done. Operation of CCP1 could be affected if it is using the same timer as a

time base.

Compare Capture CCP1 can be configured for the Special Event Trigger to reset TMR1 or TMR3

(depending upon which time base is used). Operation of CCP2 could be affected if it is

using the same timer as a time base.

Compare Compare Either module can be configured for the Special Event Trigger to reset the time base.

Automatic A/D conversions on CCP2 trigger event can be done. Conflicts may occur if

both modules are using the same time base.
