(4) Analog input channel specification register (ADS)
320
Cautions 1. Be sure to clear bits 3 to 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.
2 Set a channel to be used for A/D conversion in the input mode by using port mode register 2
3. If data is written to ADS, a wait cycle is generated. Do not write data to ADS when the CPU is
(PM2).
operating on the subsystem clock and the peripheral hardware clock is stopped. For details,
see CHAPTER 35 CAUTIONS FOR WAIT.
