(5) Analog input channel specification register (ADS)
Note Setting permitted in products with operational amplifier
Cautions 1. Be sure to clear bits 4, 5, and 7 to “0”.
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.
Remark A/D converter analog input pins differ depending on products.

2. Set a channel to be used for A/D conversion in the input mode by using port mode registers 1,
3. Set ADS after PGA operation setting when selecting the PGA output signal as analog input
4. If data is written to ADS, a wait cycle is generated. Do not write data to ADS when the
