Analog-to-Digital Converter (ATD)
Registers and Reset Initialization
CCF7–CCF0 — Conversion Complete Flags
Each ATD channel has a CCF flag. A CCF flag is set at the end of the
conversion on that channel. Clear a CCF flag by reading status
register 1 with the flag set and then reading the result register of that
channel. When the fast flag clear enable bit, AFFC, is set, reading the
result register clears the associated CCF flag even if the status
register has not been read.
