PIC18F1230/1330
The analog reference voltage is software selectable to
the device’s positive supply voltage (V
voltage level on the RA4/T0CKI/AN2/V
The A/D Converter has a unique feature of being able
to operate while the device is in Sleep mode. To
operate in Sleep, the A/D conversion clock must be
derived from the A/D Converter’s internal RC oscillator.
The output of the sample and hold is the input into the
A/D Converter, which generates the result via succes-
sive approximation.

complete,
A device Reset forces all registers to their Reset state.
This forces the A/D module to be turned off and any
conversion in progress is aborted.
Each port pin associated with the A/D Converter can be
configured as an analog input or as a digital I/O. The
ADRESH and ADRESL registers contain the result of
the A/D conversion. When the A/D conversion is
ADRESH:ADRESL register pair, the GO/DONE bit
(ADCON0 register) is cleared and A/D Interrupt Flag bit,
ADIF, is set. The block diagram of the A/D module is
shown in Figure 16-1.
