The Analog-to-Digital (A/D) Converter module has five
inputs for the PIC18F2X8 devices and eight for the
PIC18F4X8 devices. This module has the ADCON0
and ADCON1 register definitions that are compatible
with the PICmicro
The A/D allows conversion of an analog input signal to
a corresponding 10-bit digital number.

The A/D module has four registers. These registers are:
• A/D Result High Register (ADRESH)
• A/D Result Low Register (ADRESL)
• A/D Control Register 0 (ADCON0)
• A/D Control Register 1 (ADCON1)
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.
