16.0
The Analog-to-Digital (A/D) Converter module has
10 inputs for the 28-pin devices and 13 for the 40/44-pin
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 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)

These channels are not implemented on 28-pin devices.
Performing a conversion on unimplemented channels will return a floating input measurement.
Unimplemented: Read as ‘0’

GO/DONE: A/D Conversion Status bit
When ADON = 1:
1 = A/D conversion in progress
0 = A/D Idle
ADON: A/D On bit

The ADCON0 register, shown in Register 16-1,
controls the operation of the A/D module. The
ADCON1 register, shown in Register 16-2, configures
the functions of the port pins. The ADCON2 register,
shown in Register 16-3, configures the A/D clock
source, programmed acquisition time and justification.
