20.7
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 ACQT3:ACQT0 and
ADCS2:ADCS0 bits in ADCON2 should be updated in
accordance with the power-managed mode clock that
will be used. After the power-managed mode is entered
(either of the power-managed Run modes), an A/D
acquisition or conversion may be started. Once an
acquisition or conversion is started, the device should
continue to be clocked by the same power-managed
mode clock source until the conversion has been com-
pleted. If desired, the device may be placed into the
corresponding power-managed Idle mode during the
conversion.
If the power-managed mode clock frequency is less
than 1 MHz, the A/D RC clock source should be
selected.
Operation in Sleep mode requires the A/D RC clock to
be selected. If bits ACQT3:ACQT0 are set to ‘0000’
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
and SCS bits in the OSCCON register must have
already been cleared prior to starting the conversion.
DS39616C-page 258
Note:
Operation in Power-Managed
Modes
The A/D can operate in Sleep mode only
when configured for Single-Shot mode. If
the part is in Sleep mode, and it is possible
for a source other than the A/D module to
wake the part, the user must poll
ADCON0<GO/DONE> to ensure it is clear
before reading the result.
Preliminary

The ANSEL0, ANSEL1, TRISA and TRISE registers all
configure the A/D port pins. The port pins needed as
analog inputs must have their corresponding TRIS bits
set (input). If the TRIS bit is cleared (output), the digital
output level (V
The A/D operation is independent of the state of the
ANSEL0, ANSEL1 and TRIS bits.
