18.0
The Analog-to-Digital (A/D) converter module has five
inputs for the PIC18F2X39 devices and eight for the
PIC18F4X39 devices. This module has the ADCON0
and ADCON1 register definitions that are compatible
with the mid-range A/D module.
The A/D allows conversion of an analog input signal to
a corresponding 10-bit digital number.

ADON: A/D On bit
1 = A/D converter module is powered up
0 = A/D converter module is shut-off and consumes no operating current

The A/D module has four 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)
The ADCON0 register, shown in Register 18-1, con-
trols the operation of the A/D module. The ADCON1
register, shown in Register 18-2, configures the
functions of the port pins.
