The analog-to-digital (A/D) converter module has
twelve analog inputs for the PIC17C75X devices.
The A/D allows conversion of an analog input signal to
a corresponding 10-bit digital number. The output of the
sample and hold is the input into the converter, which
generates the result via successive approximation.
The analog reference voltages (positive and negative
supply) are software selectable to either the device’s
supply voltages (AV
the RG3/AN0/V
The A/D converter has a unique feature of being able
to operate while the device is in SLEEP mode. To oper-
ate in sleep, the A/D clock must be derived from the
A/D’s internal RC oscillator.

The A/D module has four registers. These registers
are:
The ADCON0 register, shown in Figure 16-1, controls
the operation of the A/D module. The ADCON1 regis-
ter, shown in Figure 16-2, configures the functions of
the port pins. The port pins can be configured as ana-
log inputs (RG3 and RG2 can also be the voltage refer-
ences) or as digital I/O.
