STATUS_EEPROM

(read only)

This read-only bit indicates the status of the data transferred between the EEPROM and the

buffer register bank during the writing and reading of the EEPROM. This signal is also

available at the STATUS0 pin when Register 0x232[4] is set.

0: data transfer is complete.

1: data transfer is not complete.

EEPROM data error

(read only)

This read-only bit indicates an error during the data transfer between the EEPROM and the buffer.

0: no error; data is correct.

1: incorrect data detected.

SOFT_EEPROM

When the EEPROM_SEL pin is tied low, setting the SOFT_EEPROM bit resets the AD9523 using

the settings saved in EEPROM.

1: soft reset with EEPROM settings (self-clearing).

Enable EEPROM write

Enables the user to write to the EEPROM.

0: EEPROM write protection is enabled. User cannot write to EEPROM (default).

1: EEPROM write protection is disabled. User can write to EEPROM.

REG2EEPROM

Transfers data from the buffer register to the EEPROM (self-clearing).

1: setting this bit initiates the data transfer from the buffer register to the EEPROM (writing

process); it is reset by the I²C master after the data transfer is done.
