19.7
An A/D conversion can be started by the “Special Event
Trigger” of the ECCP1 module. This requires that the
ECCP1M3:ECCP1M0 bits (ECCP1CON<3:0>) be
programmed 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

Use of the ECCP1 Trigger
These bits are unimplemented on PIC18F2682/2685 devices; always maintain these bits clear.
These pins may be configured as port pins depending on the oscillator mode selected.
RE3 port bit is available only as an input pin when the MCLRE Configuration bit is ‘0’.
These registers are not implemented on PIC18F2682/2685 devices.

desired location). The appropriate analog input
channel 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.
