17.0
The analog-to-digital (A/D) converter module has 8
inputs for the PIC18C601 devices and 12 for the
PIC18C801 devices. This module has the ADCON0,
ADCON1, and ADCON2 registers.
The A/D allows conversion of an analog input signal
to a corresponding 10-bit digital number.

GO/DONE: A/D Conversion Status bit
When ADON = 1:
1 = A/D conversion in progress. Setting this bit starts an A/D conversion cycle. This bit is
0 = A/D conversion not in progress
ADON: A/D On bit
1 = A/D converter module is operating
0 = A/D converter module is shut-off and consumes no operating current

CHS2
The A/D 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)
The ADCON0 register, shown in Register 17-1, controls
the operation of the A/D module. The ADCON1 register,
shown in Register 17-2, configures the functions of the
port pins. The ADCON2, shown in Register 16-3, config-
ures the A/D clock source and justification.
