PIC16F785/HV785
12.3
The A/D Converter module can operate during Sleep.
This requires the A/D clock source to be set to the F
option. When the RC clock source is selected, the A/D
waits one instruction before starting the conversion.
This allows the SLEEP instruction to be executed, thus
eliminating much of the switching noise from the con-
version. When the conversion is complete, the GO/
DONE bit is cleared and the result is loaded into the
ADRESH:ADRESL registers. If the A/D interrupt is
enabled (ADIE and PEIE bits set), the device awakens
from Sleep. If the GIE bit of the INTCON Register is set,
the program counter is set to the interrupt vector
(0004h). If GIE is clear, the next instruction is executed.
If the A/D interrupt is not enabled, the A/D module is
turned off, although the ADON bit remains set.

When the A/D clock source is something other than
RC, a SLEEP instruction causes the present conversion
to be aborted and the A/D module is turned off. The
ADON bit remains set.
