register is set after the fourth conversion in a sequence to signal the
availability of data in the result registers.The result registers are written
during a portion of the system clock cycle when reads do not occur, so
there is no conflict. A conversion sequence can repeat continuously or
stop after one iteration.
sequence. In this example, synchronization is referenced to the system
E clock.
In addition to the conversion complete status flag, ADCTL bits select
single or continuous conversions, whether conversions are performed
on single or multiple channels, and the analog input(s) to be converted.
Single or continuous conversions are selected by the SCAN bit. Clearing
the SCAN bit selects the single conversion option, in which results are
written to each of the four result registers one time. The first result is
stored in A/D result register 1 (ADR1), and the fourth result is stored in
ADR4. All conversion activity is then halted until the ADCTL register is
written again. In the continuous mode (SCAN =1), conversion activity
does not stop. The fifth conversion is stored in register ADR1
(overwriting the first conversion result), the sixth conversion overwrites
ADR2, and so on.
