(1) A/D converter mode register (ADM)
164
Address: FF80H
Symbol
ADM
This register sets the conversion time for analog input to be A/D converted, and starts/stops conversion.
ADM can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Remarks 1. f
Note 1. Even when the ADCE = 0 (comparator operation stopped), the A/D conversion operation starts if
