Power Management Data
The Power Management (PM) Data register set is comprised of 16 eight-bit registers, providing more detailed
power management information about the device. All 16 registers will return 00h by default. The first eight registers
are assigned to single function devices, and the second eight are reserved for use by multifunction devices (see
Table 17). The FW322 supports programmability, via the serial EEPROM, of the first eight registers in the PM data
complex. Software uses the DATA_SELECT and DATA_SCALE fields within the Power Management Control and
Status register to select and scale the desired PM data entry. Note that if the serial EEPROM is used to program
nonzero values into PM DATA, then the AUX_PWR field should be programmed to a zero value via the serial
EEPROM and vice versa. This is to comply with the PCI Specification, which states that these two functions must
be implemented mutually exclusive of one another. The FW322 does not enforce this, and therefore, it is up to the
creator of the serial EEPROM image to ensure that these two fields are used mutually exclusive of one another.
