Note 1: Always set bit 0 in ADCCR2 to “0” and set bit 4 in ADCCR2 to “1”.
Note 2: When a read instruction for ADCCR2, bit 6 to 7 in ADCCR2 read in as undefined data.
Note 3: After STOP or SLOW/SLEEP mode are started, AD converter control register 2 (ADCCR2) is all initialized and no data
Note 1: Settings for “−” in the above table are inhibited.
Note 2: Set conversion time by Supply Voltage(VDD) as follows.
Note 1: The ADCDR2<EOCF> is cleared to “0” when reading the ADCDR1.
Note 2: ADCDR2<ADBF> is set to “1” when AD conversion starts and cleared to “0” when the AD conversion is finished. It
Note 3: If a read instruction is executed for ADCDR2, read data of bits 7, 6 and 3 to 0 are unstable.

can be written in this register. Therefore, to use AD converter again, set the ADCCR2 newly after returning to NORMAL1
or NORMAL2 mode.
Therefore, the AD conversion result should be read to ADCDR2 more first than ADCDR1.
