12.1 Configuration
12. 8-Bit AD Converter (ADC)
12.2 Control
AD Converter Control Register 1
ADCCR1
(000EH)
The AD converter consists of the following four registers:
Note 1: Select analog input when AD converter stops (ADCDR2<ADBF> = “0”).
Note 2: When the analog input is all use disabling, the ADCCR1<AINDS> should be set to “1”.
Note 3: During conversion, do not perform output instruction to maintain a precision for all of the pins. And port near to analog
Note 4: The 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 register 1 (ADCCR1) is all initialized and no data
Note 7: Always set bit 5 in ADCCR1 to “1” and set bit 6 in ADCCR1 to “0”.
