PIC18F47J53 FAMILY
22.0 10/12-BIT ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
The Analog-to-Digital (A/D) Converter module in the
PIC18F47J53 family of devices has 10 inputs for the
28-pin devices and 13 inputs for the 44-pin devices.
This module allows conversion of an analog input
signal to a corresponding 10 or 12-bit digital number.
The module has these registers:
• A/D Control Register 0 (ADCON0)
• A/D Control Register 1 (ADCON1)
• A/D Port Configuration Register 0 (ANCON0)
• A/D Port Configuration Register 1 (ANCON1)
• A/D Result Registers (ADRESH and ADRESL)
• A/D Trigger Register (ADCTRIG)
• Configuration Register 3 High (ADCSEL,
CONFIG3H<1>)
The ADCON0 register, shown in Register 22-1,
controls the operation of the A/D module.
The ADCON1 register, shown in Register 22-1, config-
ures the A/D clock source, programmed acquisition
time and justification. The ANCON0 and ANCON1
registers, in Register 22-1 and Register 22-2, configure
the functions of the port pins.
The ADCSEL Configuration bit (CONFIG3H<1>) sets
the module for 10 or 12-bit conversions. The 10-Bit
Conversion mode is useful for applications that favor
conversion speed over conversion resolution.
