12-BIT ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
The Analog-to-Digital (A/D) Converter module has
10 inputs for the PIC18F2423/2523 devices and 13 for
the PIC18F4423/4523 devices. This module allows
conversion of an analog input signal to a corresponding
12-bit digital number.
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)
Of the ADCONx registers:
ADCON0 (shown in Register 2-1) – Controls the
module’s operation
ADCON1 (Register 2-2) – Configures the
functions of the port pins
ADCON2 (Register 2-3) – Configures the A/D
clock source, programmed acquisition time and
justification

GO/DONE: A/D Conversion Status bit
When ADON = 1:
1 = A/D conversion in progress
0 = A/D Idle
bit 0
ADON: A/D On bit
1 = A/D Converter module is enabled
0 = A/D Converter module is disabled
Note 1:
These channels are not implemented on PIC18F2423/2523 devices.
2:
Performing a conversion on unimplemented channels will return a floating input measurement.
