Default status right after reset
When the automatic reading function with the AUTO pin is used, it becomes timing of SCEB to SCK as above.
It is possible to access from the register of BU6520KV/BU6521KV to EEPROM.In that case, SCEB is controlled by the
register.
After the value is set to the register, the SCEB pin is changed into the logic set at once.
