ADC configuration and operation
Every analog-to-digital conversion is an autoscan
conversion. The two user selectable general operation
modes are continuous scan and one-time scan mode.
The desired analog input port channel(s) for conversion
is(are) selected by programming analog-to-digital input
port scan-select bits in SFR ADPSS. An analog input
channel is included in the autoscan loop if the
corresponding bit in SFR ADPSS is logic 1, a channel is
skipped if the corresponding bit in SFR ADPSS is logic 0.
An autoscan is always started according to the lowest bit
position of SFR ADPSS that contains a logic 1.
An autoscan conversion is started by setting the flag
ADSST in register ADCON either by software or by an
external start signal at input pin ADEXS, if enabled.
Either no edge (external start totally disabled), a rising
edge or/and a falling edge of ADEXS is selectable for
external conversion start by the bits ADSRE and ADSFE
in register ADCON.
After completion of an analog-to-digital conversion the
10-bit result is stored in the corresponding 10-bit buffer
register. Then the next analog input is selected according
to the next higher set bit position in ADPSS, converted and
stored, and so on.
When the result of the last conversion of this autoscan loop
is stored, the ADC interrupt flag ADINT (SFR ADCON), is
set. It is not cleared by interrupt hardware - it must be
cleared by software.
