16. 10-bit AD Converter (ADC)
16.2 Register configuration
16.2 Register configuration
AD Converter Control Register 1
ADCCRA
(0026H)
The AD converter consists of the following four registers:
Note 1: Select analog input channel during AD converter stops (ADCDRL<ADBF> = "0").
Note 2: When the analog input channel is all use disabling, the ADCCRA<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 ADCCRA<ADRS> is automatically cleared to "0" after starting conversion.
Note 5: Do not set ADCCRA<ADRS> newly again during AD conversion. Before setting ADCCRA<ADRS> newly again, check
Note 6: After STOP mode is started, AD converter control register1 (ADCCRA) is all initialized and no data can be written in this
Note 7: After RESET, ADCCRA<SAIN> is initialized Reserved setting. Therfore, set the appropriate analog input channel to ADC-
Note 8: After ADCCRA is set to 00H, AD conversion can not be started for four cycles. Thus, four NOPs must be inserted before
