27.4.5.1 Alternate Sync Out
The ALTSYNC control bit (CCPxCON1[21]) allows the user to substitute a different
synchronization/trigger output in place of the timer rollover for the CCP Sync signal.
When ALTSYNC = 0, the CCP Sync output is the default timer rollover
signal in all operating modes. When ALTSYNC = 1, the synchronization
signal depends on the specific operating mode. Table 27-18
lists the alternate outputs available.
| ALTSYNC | CCSEL | MOD[3:0] | Output Signal |
|---|---|---|---|
0 | x | All | Standard (default) CCP Sync Output |
1 | 0 | 0000 | Special Event Trigger Output (Timer) |
1 | 0 | All except ‘0000’ | Output Compare Interrupt Event (Compare) |
1 | 1 | All | Input Capture Event (Capture) |
