Description
Download the factory default settings from EEPROM (Page 0 of the main block) into
operating memory. The password is also reset to the default value (0xFF).
Description
Copy the entire contents of operating memory (registers) into EEPROM (Page 1 of the main
block). The EEPROM must first be unlocked.
Description
Download the stored user settings from EEPROM (Page 1 of the main block) into operating
memory. The EEPROM must first be unlocked.
Description
Return the CRC checksum value from the EEPROM download operation.
Description
Set the address offset of the current EEPROM page.

each page erase operation. The EEPROM must first be unlocked. Page 0 and Page 1 are
reserved for storing the default settings and user settings, respectively. The user cannot
perform a page erase of Page 0 or Page 1. Page 2 and Page 3 are reserved for internal use
and their contents should not be erased.
Description
Write the password to this register two consecutive times to unlock the EEPROM and/or to
change the EEPROM password. The factory default password is 0xFF. To lock the EEPROM,
type any value other than the password to this register.
Description
Write the password to this register to unlock the trim registers for write access. Write the
trim password twice to unlock the register; write any other value to exit. The trim password
is the same as the EEPROM password.
Description
Set the number of read bytes returned when using the EEPROM_DATA_xx command.
Description
Perform a page erase on the selected EEPROM page (Page 4 to Page 15). Wait 35 ms after
