Note 1: Select analog input when AD converter stops (ADCDR2<ADBF>
Note 2: When the analog input is all use disabling, the 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
Note 4: The ADRS is automatically cleared to “0” after starting conversion.
Note 5: Do not set ADRS (ADCCR1 bit7) newly again during AD conversion. Before setting ADRS newly again, check
Note 6: After STOP or SLOW mode are started, AD converter control register 1 (ADCCR1) is all initialized.
Note 1: Settings for “  ” in the above table are inhibited.
Note 2: Set conversion time by analog reference voltage (V
Note 3: Always set bit0 in ADCCR2 to “0” and set bit4 in ADCCR2 to “1”.
Note 4: When a read instruction for ADCCR2, bit6 to bit7 in ADCCR2 read in as undefined data.
Note 5: fc; High-frequency clock [Hz]
Note 6: After STOP or SLOW mode are started, AD converter control register 2 (ADCCR2) is all initialized.
