Note 1: Do not perform the following operations on the ADCCR1 register while AD conversion is being executed
Note 2: If you want to disable all analog input channels, set AINEN to "0".
Note 3: Although analog input pins are also used as input/output ports, it is recommended for the purpose of maintaining the
Note 4: When STOP, IDLE0 or SLOW mode is started, ADRS, AMD and AINEN are initialized to "0". If you use the AD converter
Note 5: After the start of AD conversion, ADRS is automatically cleared to "0" ("0" is read).
