The selection of the automatic acquisition time and A/D
conversion clock is determined in part by the clock
source and frequency while in a power-managed mode.
If the A/D is expected to operate while the device is in
a power-managed mode, the ADCS<2:0> bits in
ADCON2 should be updated in accordance with the
clock source to be used. The ACQT<2:0> bits do not
need to be adjusted as the ADCS<2:0> bits adjust the
T
mode, an A/D acquisition or conversion may be started.
Once started, the device should continue to be clocked
by the same clock source until the conversion has been
completed.
If desired, the device may be placed into the
corresponding Idle mode during the conversion. If the
device clock frequency is less than 1 MHz, the A/D RC
clock source should be selected.
Operation in Sleep mode requires the A/D F
be selected. If bits, ACQT<2:0>, are set to ‘000’ and a
conversion is started, the conversion will be delayed
one instruction cycle to allow execution of the SLEEP
instruction and entry to Sleep mode. The IDLEN bit
(OSCCON<7>) must have already been cleared prior
to starting the conversion.

The ADCON1, TRISA, TRISB and TRISE registers all

analog inputs must have their corresponding TRIS bits
