The Analog-to-Digital (A/D) Converter module has
12 inputs for all PIC18F85J11 family devices. This
module allows conversion of an analog input signal to
a corresponding 10-bit digital number.
The module has five registers:
• A/D Result Register High Byte (ADRESH)
• A/D Result Register Low Byte (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, programmed acquisition time and justification.
