An A/D conversion can be started by the “Special Event
Trigger” of the CCP2 module. This requires that the
CCP2M3:CCP2M0 bits (CCP2CON<3:0>) be pro-
grammed as ‘1011’ and that the A/D module is enabled
(ADON bit is set). When the trigger occurs, the
GO/DONE bit will be set, starting the A/D acquisition
and conversion and the Timer1 (or Timer3) counter will
be reset to zero. Timer1 (or Timer3) is reset to automat-
ically repeat the A/D acquisition period with minimal

software overhead (moving ADRESH/ADRESL to the
desired location). The appropriate analog input chan-
nel must be selected and the minimum acquisition
period is either timed by the user, or an appropriate
T
sets the GO/DONE bit (starts a conversion).
If the A/D module is not enabled (ADON is cleared), the
“Special Event Trigger” will be ignored by the A/D
module, but will still reset the Timer1 (or Timer3)
counter.
