(6) Analog input channel specification register (ADS)
Note 1
Address: FFF31H
Symbol
ADS
This register specifies the input channel of the analog voltage to be A/D converted.
ADS can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

Note 2
Be sure to clear bits 4, 5, and 7 to “0”.
Set a channel to be used for A/D conversion in the input mode by using port mode
registers 2, 8, and 15 (PM2, PM8, PM15).
Do not set the pin that is set by ADPC as digital I/O by ADS.
Select the output signal (PGAO) of the programmable gain amplifier from PGAI pin as
the analog input after setting the operation of the programmable gain amplifier (refer to
12.4.1 Basic operations of A/D converter).
