(3) 10-bit A/D conversion result register (ADCR)
(4) Analog input channel specification register (ADS)
ADS
Use the ADCR register in the same manner as during A/D converter basic operation (see 10.3 (3) 10-bit A/D
conversion result register (ADCR)).
Caution When using a temperature sensor, use the result of the second or later A/D conversion for
This register specifies the channel from which an analog voltage to be A/D-converted is input, in the same
manner as during A/D converter basic operation. When a temperature sensor is used, however, some settings
differ from those of A/D converter basic operation.
ADS can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Caution Be sure to clear bits 4 to 6 to “0”.
