status
If EEPROM load data mode has been selected with pins LM0,1, this register indicates the checksum status of
the loading process from the external EEPROM.
checksum status
Set to 1 if the data load is successful (ensured by the CRC-16 checksum encryption
over the 10,496 bytes of configuration data) in the EEPROM load data mode.

If EEPROM load data mode has been selected with pins LM0,1, this register indicates the readiness of the
EEPROM controller and can be used to turn on and off the writing feature to the external EEPROM.
ready
writable
Set to 1 when the controller’s page FIFO buffer is ready to be used for further read and write
data from/to the external EEPROM.
This bit is used to enable/disable the writing feature to the external EEPROM. Write ‘1’ to
this bit makes the EEROM writable. Writing ‘0’ to this bit makes the EEPROM not writable.

trig the EEPROM controller to write the contents in the 64-byte page FIFO buffer to a certain
page of the external EEPROM.
trig the EEPROM controller to read and copy the 64-byte content of certain page of the
external EEPROM into the page FIFO buffer.

Page number
If EEPROM load data mode has been selected with pins LM0,1, this register is used to specify the index of the
page of the EEPROM for the further read and write command. The valid value is from 0 to 163.
