(Refer to the following table about the con-
version time)
Note 1: Always set bit0 in ADCCR2 to "0" and set bit4 in ADCCR2 to "1".
Note 2: When a read instruction for ADCCR2, bit6 to 7 in ADCCR2 read in as undefined data.
Note 3: After STOP or SLOW/SLEEP mode are started, AD converter control register2 (ADCCR2) is all initialized and no data can
be written in this register. Therfore, to use AD converter again, set the ADCCR2 newly after returning to NORMAL1 or
NORMAL2 mode.

Note 1: Setting for "−" in the above table are inhibited.
Note 2: Set conversion time setting should be kept more than the following time by Analog reference voltage (VAREF) .
-
VAREF = 4.5 to 5.5 V
-
VAREF = 2.7 to 5.5 V
-
VAREF = 1.8 to 5.5 V
