PMC/PCI Interface: PCI9060ES Initialization
PmT1 and PmE1 User’s Manual 10002367-02
7-4
The serial EEPROM may be reprogrammed to configure the PCI bridge in other ways. Bits
(27:24) of the PCI9060ES EEPROM control register (C100,00EC
16
) are used for reading and
writing the EEPROM. Refer to the NS93CS46 data sheet listed in
Tab le 1 -5 for a description of
the EEPROM’s programming instructions, and the PCI9060ES data sheet for the sequence
in which the data is stored.
