Reset, Clocking, and Initialization
The attributes should be programmed as follows: alternate configuration space (ACS) should be cleared
(0b0), byte enables should be all ones, and continue (CONT) should be set.
After the first 3 bytes, 4 bytes of data should hold the desired value of the reset configuration word. The
boot sequencer assumes that a big-endian address is stored in the EEPROM.
IMMRBAR value is prepended to the EEPROM address to generate the complete memory-mapped
register’s address.

and additional initialization data, and CRC. In this example, it is assumed that the EEPROM contains
information additional to the reset configuration words, which should be loaded in the functional state after
the device completes its reset flow.
