9.1
When configuring and using the ADC the following
functions must be considered:
• Port configuration
• Channel selection
• ADC voltage reference selection
• ADC conversion clock source
• Interrupt control
• Results formatting
9.1.1
The ADC can be used to convert both analog and
digital signals. When converting analog signals, the I/O
pin should be configured for analog by setting the
associated TRIS and ANSEL bits. Refer to Section 6.0
“I/O Ports” for more information.
9.1.2
The CHS bits of the ADCON0 register determine which
channel is connected to the sample and hold circuit.
When changing channels, a delay is required before
starting the next conversion. Refer to Section 9.2
“ADC Operation” for more information.

For faster conversion times, the selection of another clock source is recommended.
When the device frequency is greater than 1 MHz, the F
conversion will be performed during Sleep.
PORT CONFIGURATION
Analog voltages on any pin that is defined
as a digital input may cause the input
buffer to conduct excess current.

9.1.3
The ADREF bits of the ADCON1 register provides
control of the positive voltage reference. The positive
voltage reference can be either V
voltage source or the internal Fixed Voltage Reference.
The negative voltage reference is always connected to
the ground reference. See Section 10.0 “Fixed
Voltage Reference” for more details on the Fixed
Voltage Reference.
9.1.4
The source of the conversion clock is software select-
able via the ADCS bits of the ADCON1 register. There
are seven possible clock options:
• F
• F
