Description
Return the CRC checksum value from the EEPROM download operation.
Description
These bits set the number of read bytes returned when using the EEPROM_DATA_xx commands.
Description
These bits set the address offset of the current EEPROM page.
Description
Perform a page erase on the selected EEPROM page. (Wait 35 ms after each page erase operation.)
EEPROM must first be unlocked. Page 0 and Page 1 erase are allowed only in manufacturing test mode.
Description
Write the password to this register to unlock EEPROM and/or to change the EEPROM password.
Description
Write the password to this register to unlock the trim registers for write access. Write the trim password
twice (default 0x00) to unlock the register; write any other value to exit.
