5.1.5 PCI BASE IO ADDRESS REGISTER ( PBIO ) ( Offset 13h-10h )
bit 0 : IO/Memory Space Indicator, fixed to 1 in this field will map into the IO space. This is a read only field.
bit 7 - 1 : not used, all 0 when read
bit 31 - 8 : Defines the address assignment mapping of MX98715A CSR registers.
5.1.6 PCI Base Memory Address Register ( PBMA ) ( Offset 17h-14h )
bit 0 : Memory Space Indicator, fixed to 0 in this field will map into the memory space. This is a read only field.
bit 6 - 1 : not used, all 0 when read
bit 31 - 7 : Defines the address assignment mapping of MX98715A CSR registers.
5.1.7 PCI SUBSYSTEM ID REGISTER ( PSID ) ( Offset 2Ch-2Fh )
This register is used to uniquely identify the add-on board or subsystem where the NIC controller resides. Values in
this register are loaded directly from external serial EEPROM after system reset automatically. Word location 36h of
EEPROM is subsystem vendor ID and location 35h is sub-system ID.
