A multiplexer allows the single A/D converter to select one of 16 analog input signals.
The A/D converter control logic implements automatic conversion sequences on a selected channel
four times or on four channels once each. A write to the ADCTL register initiates conversions and, if
made while a conversion is in progress, a write to ADCTL also halts that conversion operation, sets
CCF, and proceeds to the next instruction.
When the SCAN bit is zero, four requested conversions are performed, once each, to fill the four result
registers. When SCAN is one, conversions continue in a round-robin fashion with the result registers
being updated as new data becomes available. When the MULT bit is zero, the A/D converter system
is configured to perform conversions on each channel in the group of four channels specified by the CD
and CC channel select bits.
