AD Converter Control Register 1
ADCCR1
(000EH)
The AD converter consists of the following four registers:
Note 1: Select analog input channel during AD converter stops (ADCDR2<ADBF> = "0").
Note 2: When the analog input channel is all use disabling, the ADCCR1<AINDS> should be set to "1".
Note 3: During conversion, Do not perform port output instruction to maintain a precision for all of the pins because analog input
Note 4: The ADCCR1<ADRS> is automatically cleared to "0" after starting conversion.
Note 5: Do not set ADCCR1<ADRS> newly again during AD conversion. Before setting ADCCR1<ADRS> newly again, check
Note 6: After STOP or SLOW/SLEEP mode are started, AD converter control register1 (ADCCR1) is all initialized and no data can
