(2) Analog input channel specification register (ADS)
Cautions 1. Be sure to clear bits 3 to 7 of ADS to 0.
This register specifies the input port of the analog voltage to be A/D converted.
ADS can be set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
2. If data is written to ADS, a wait cycle is generated. Do not write data to ADS when the CPU is
operating on the subsystem clock and the X1 input clock is stopped.
