20.0
The analog-to-digital (A/D) converter module has
12 inputs for the PIC18F6525/6621 devices and 16 for
the PIC18F8525/8621 devices. This module allows
conversion of an analog input signal to a corresponding
10-bit digital number.
A new feature for the A/D converter is the addition of
programmable acquisition time. This feature allows the
user to select a new channel for conversion and setting
the GO/DONE bit immediately. When the GO/DONE bit
is set, the selected channel is sampled for the
programmed acquisition time before a conversion is
actually started. This removes the firmware overhead
that may have been required to allow for an acquisition
(sampling) period (see Register 20-3 and Section 20.5
“A/D Conversions”).

GO/DONE: A/D Conversion Status bit
When ADON = 1:
1 = A/D conversion in progress (setting this bit starts the A/D conversion which is automatically
0 = A/D conversion not in progress
ADON: A/D On bit
1 = A/D converter module is enabled
0 = A/D converter module is disabled

The module has five registers:
• A/D Result High Register (ADRESH)
• A/D Result Low Register (ADRESL)
• A/D Control Register 0 (ADCON0)
• A/D Control Register 1 (ADCON1)
• A/D Control Register 2 (ADCON2)
The ADCON0 register, shown in Register 20-1,
controls the operation of the A/D module. The
ADCON1 register, shown in Register 20-2, configures
the functions of the port pins. The ADCON2 register,
shown in Register 20-3, configures the A/D clock
source, justification and auto-acquisition time.
