Checksum
Checks whether the 7600 bytes firmware configuration data is loaded successfully.
0 = Fail, 1 = Success
READY
Indicates if field upgrade is ready to begin, normally is set to 1 at 3 milliseconds (3ms) after the reset.
0 = Not ready
1 = Ready
Load_Complete
Indicates whether the loading of 7600 bytes firmware configuration data is complete.
0 = Not complete
1 = Complete

Field upgrade of firmware configuration data
Writes the firmware configuration data (7600 bytes) to this register one byte at a time to complete data loading.
Only the last written byte can be read from this register, regardless how many times of reads performed.

Lower 8 bits of byte count for firmware configuration data
Higher 5 bits of byte count for firmware configuration data
Reads this register for how many bytes of 7600 bytes firmware configuration data has been loaded through the
register Field_Upgrade_Data.

If bit READY of the register Field Upgrade Status is set to 1, user can write three values to this register con-
secutively, with no intervening read/writes from/to other registers to start the process of field upgrade. 7600
bytes firmware configuration data can only start loading after the three values are written successfully.
