(5) Steps (2) to (4) are repeated cyclically as long as the ADST bit remains set to “1.”
To stop the A/D converter, software must clear the ADST bit to “0.”
Regardless of which channel is being converted when the ADST bit is cleared to “0,” when the
ADST bit is set to “1” again, conversion begins from the the first selected channel (AN
