ANALOG-TO-DIGITAL
CONVERTER (A/D) MODULE
The analog-to-digital (A/D) converter module has four
inputs.
The A/D allows conversion of an analog input signal to
a corresponding 8-bit digital number (refer to Applica-
tion Note AN546 for use of A/D Converter). The output
of the sample and hold is the input into the converter,
which generates the result via successive approxima-
tion. The analog reference voltage is software select-
able to either the device’s positive supply voltage (V
DD
)
or the voltage level on the RA3/AN3/V
REF
pin.
The A/D converter has a unique feature of being able to
operate while the device is in SLEEP mode. To operate
in sleep, the A/D conversion clock must be derived from
the A/D’s internal RC oscillator.
Additional information on the A/D module is available in
the PICmicro Mid-Range Reference Manual,
(DS33023).
The A/D module has three registers. These registers
are:
A/D Result Register (ADRES)
A/D Control Register 0 (ADCON0)
A/D Control Register 1 (ADCON1)
A device reset forces all registers to their reset state.
This forces the A/D module to be turned off, and any
conversion is aborted.
The ADCON0 register, shown in Figure 8-1, controls
the operation of the A/D module. The ADCON1 regis-
ter, shown in Figure 8-2, configures the functions of the
port pins. The port pins can be configured as analog
inputs (RA3 can also be a voltage reference) or as dig-
ital I/O.
