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)

These channels are not implemented on PIC18F2423/2523 devices.
Performing a conversion on unimplemented channels will return a floating input measurement.
