Description

B00

[0]

STATUS_EEPROM

(read-only)

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

when 0x01D[7] is set.

[0] = 0; data transfer is done.

[0] = 1; data transfer is not done.

B01

[0]

EEPROM

data error

(read-only)

This read-only register indicates an error during the data transferred between the EEPROM and the buffer.

[0] = 0; no error. Data is correct.

[0] = 1; incorrect data detected.

B02

[1]

Soft_EEPROM

When the EEPROM pin is tied low, setting Soft_EEPROM resets the AD9520 using the settings saved in

EEPROM.

[1] = 1; soft reset with EEPROM settings (self-clearing).

B02

[0]

Enable EEPROM

write

Enables the user to write to the EEPROM.

[0] = 0; EEPROM write protection is enabled. User cannot write to EEPROM (default).

[0] = 1; EEPROM write protection is disabled. User can write to EEPROM.

B03

[0]

REG2EEPROM

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

[0] = 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.
