reading the first byte, the Am79C973/Am79C975 con-
troller reads in three more bytes by incrementing the
lower portion of the ROM address. After the last byte is
strobed in, TRDY will be asserted on clock 50. When
the host tries to perform a burst read of the Expansion
ROM, the Am79C973/Am79C975 controller will dis-
connect the access at the second data phase.
The host must program the Expansion ROM Base Ad-
dress register in the PCI configuration space before the
first access to the Expansion ROM. The Am79C973/
