An A/D conversion can be started by the “special event
trigger” of the CCP1 module. This requires that the
CCP1M3:CCP1M0 bits (CCP1CON<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 auto-
matically repeat the A/D acquisition period with minimal

x = unknown, u = unchanged, q = depends on CONFIG1H<3:0>, – = unimplemented, read as ‘0’.
Shaded cells are not used for A/D conversion.
RA5 port bit is available only as an input pin when the MCLRE bit in the configuration register is ‘0’.
RA6 and TRISA6 are available only when the primary oscillator mode selection offers RA6 as a port pin; otherwise, RA6
always reads ‘0’, TRISA6 always reads ‘1’ and writes to both are ignored (see CONFIG1H<3:0>).
RA7 and TRISA7 are available only when the internal RC oscillator is configured as the primary oscillator in
CONFIG1H<3:0>; otherwise, RA7 always reads ‘0’, TRISA7 always reads ‘1’ and writes to both are ignored.

desired location). The appropriate analog input
channel must be selected and the minimum acquisition
period is either timed by the user, or an appropriate

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.
