PIC18F6525/6621/8525/8621
The analog reference voltage is software selectable to
either the device’s positive and negative supply voltage
(V
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’s internal RC oscillator.
The output of the sample and hold is the input into the
converter which generates the result via successive
approximation.

A device Reset forces all registers to their Reset state.
This forces the A/D module to be turned off and any
conversion is aborted.
Each port pin associated with the A/D converter can be
configured as an analog input (RA3 can also be a
voltage reference), 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 complete, the
result is loaded into the ADRESH/ADRESL registers,
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 20-1.
