C. Design Notes
1. Power Management Interface Specification version support
Design Issue:
The PCI 9030 Data Book indicates compliance with the PCI
Power Management Interface Specification revision 1.1, however the PMC
register description is compliant with revision 1.0. The PCI 9030 can support
either revision. The only differences between these revisions, with respect to
PCI 9030 support, are the Version bits [2:0] value (programmable by EEPROM),
and the descriptions for bits [8:6, 4] for which the values are read-only and return
a value of 0 regardless of revision. The Version bits value (001b or 010b), which
has no effect on PCI 9030 operation, is used by software to determine PMC
register format.
Recommendation:
PMC register descriptions for revisions 1.0 and 1.1 are
listed below. If revision 1.1 rather than revision 1.0 is to be supported, program
the serial EEPROM with the Version value (010b) to overwrite the PMC register
default value, by changing the 32-bit value at EEPROM offset 18h from
48014801h to 48024801h.
