In this case, the BROM page mode is used. Before either to read or write BROM, the appropriate ROM

page must be set in the BPAGE (page3, offset 02h) register first. The RTL8019AS will always reflect the

content of BPAGE onto the BA14-21 bus. When RTL8019AS decodes a valid BROM read or write

command, it asserts BCSB low. Note the flash memory write must be enabled through the RTL8019AS's

FMWP register before the host's flash write command.
