Notes 1. The mark around the status value means the reset status by the "L" level is input to AC pin.

2. The page in which data is written is controlled by the DAF bit. When set to "0", data is written into page 0, whereas when set to "1", data is written

into page 1.

3. Registers marked with (Note 3) are found only in page 0, therefore the register value does not change when the DAF bit is set to "1".
