2.8
An A/D conversion can be started by the Special Event
Trigger of the ECCP2 module. This requires that the
CCP2M<3:0> bits (CCP2CON<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 automatically repeat the
A/D acquisition period with minimal software overhead
(moving ADRESH:ADRESL to the desired location).

Use of the ECCP2 Trigger
PORTA<7:6> and their direction bits are individually configured as port pins based on various primary
oscillator modes. When disabled, these bits read as ‘0’.
These registers are not implemented on 64-pin devices.
For these Reset values, see the “PIC18F6390/6490/8390/8490 Data Sheet” (DS39629).

The appropriate analog input channel must be selected
and the minimum acquisition period is either timed by
the user, or an appropriate T
the Special Event Trigger 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.
