Write-only flag. The S-35390A H Series initializes by writing "1" in this register. *2. Scratch bit. This is a register which is available for read / write operations and can be used by users freely. *3. Read-only flag. Valid only when using the alarm function. When the alarm time matches, this flag is set to "1", and it is cleared to "0" when reading. *4. Read-only flag. "POC" is set to "1" when power is applied. It is cleared to "0" when reading. Regarding "BLD", refer to " Low Power Supply Voltage Detection Circuit". *5. Test bit for SII. Be sure to set to "0" in use. *6. No effect when writing. It is "0" when reading. |
