18.0
The analog-to-digital (A/D) converter module has
twelve inputs for the PIC18C658 devices and sixteen
for the PIC18C858 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 auto-
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

The A/D module has five registers:
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 func-
tions of the port pins. The ADCON2, shown in Register
16-3, configures the A/D clock source and justification.
