Bits Name Description
0xB00
[7:1]
Unused
Unused.
0 STATUS_EEPROM
(read only)
This read-only register indicates the status of the data transfer between the EEPROM and the buffer
register bank during the writing and reading of the EEPROM. This signal is also available at the STATUS
pin when Register 0x01D[7] is set.
0: data transfer is complete.
1: data transfer is not complete.
0xB01 [7:1] Unused Unused.
0 EEPROM data error
(read only)
This read-only register indicates an error during the data transfer between the EEPROM and the buffer.
0: no error. Data is correct.
1: incorrect data detected.
0xB02 [7:2] Unused Unused.
1 SOFT_EEPROM When the EEPROM pin is tied low, setting SOFT_EEPROM resets the AD9520 using the settings saved in
the EEPROM.
1: soft reset with EEPROM settings (self-clearing).
0 Enable EEPROM
write
Enables the user to write to the EEPROM.
0: EEPROM write protection is enabled. User cannot write to the EEPROM (default).
1: EEPROM write protection is disabled. User can write to the EEPROM. Once an EEPROM save/load transfer is
complete, the user must wait a minimum of 10 µs before starting the next EEPROM save/load transfer.
0xB03 [7:1] Unused Unused.
0 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 complete. Once an EEPROM save/load transfer is
complete, the user must wait a minimum of 10 µs before starting the next EEPROM save/load transfer.
