11 ANALOG-TO-DIGITAL CONVERTER (ADC)
The completion of the 8-bit ADC conversion is flagged by
ADCI in the ADCON register and the result is stored in
Special Function Register ADCH.
An ADC conversion in progress is unaffected by an
external or software ADC start. The result of a completed
conversion remains unaffected provided ADCI = 1. While
ADCS = 1 or ADCI = 1, a new ADC start will be blocked
and consequently lost.
An ADC conversion already in progress is aborted when
the Idle or Power-down mode is entered. The result of a
completed conversion (ADCI = 1) remains unaffected
when entering the Idle mode.
If ADCI is cleared by software and ADCS is set at the same
time, a new analog-to-digital conversion with the same
channel number, may be started. However, it is
recommended to reset ADCI before ADCS is set.
11.1
Analog input pins
The analog input circuitry consists of an 8-input analog
multiplexer and an ADC with 8-bit resolution. The analog
reference voltage and analog power supplies are
connected via separate input pins. The conversion takes
24 machine cycles i.e. 18
μ
s at an oscillator frequency of
16 MHz.
The ADC is controlled using the ADC Control Register
(ADCON). Input channels are selected by the analog
multiplexer, using bits AADR.0 to AADR.2 in ADCON.
