12.0
The Analog-to-Digital (A/D) Converter module has
11 inputs for the PIC16F737 and PIC16F767 devices
and 14 for the PIC16F747 AND PIC16F777 devices.
The A/D converter allows conversion of an analog input
signal to a corresponding 10-bit digital number.
A new feature for the A/D converter is the addition of
programmable acquisition time. This feature allows the
user to select a new channel for conversion and to set
the GO/DONE bit immediately. When the GO/DONE bit
is set, the selected channel is sampled for the
programmed acquisition time before a conversion is
actually started. This removes the firmware overhead
required to allow for an acquisition (sampling) period
(see Register 12-3 and Section 12.2 “Selecting and
Configuring Automatic Acquisition Time”).

ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
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)
The ADCON0 register, shown in Register 12-1, controls
the operation of the A/D module and clock source. The
ADCON1 register, shown in Register 12-2, configures
the functions of the port pins, justification and voltage
reference
Register 12-3, configures the programmed acquisition
time.
