Base Address (BA) — R/W. Software programs this field with the base address of
this region.
I/O Size (IOSIZE) — RO. I/O space size is 32 Bytes.
Memory / IO Space (MIOS) — RO. Set to ‘1’ indicating an IO Space BAR.
Subsystem ID (SID) — RO. This value may be loaded automatically from the NVM
Word 0Ch upon power up depending on the "Load Subsystem ID" bit field in NVM word
0Ah. A value of 8086h is default for this field upon power up if the NVM does not
respond or is not programmed. All functions are initialized to the same value.
Subsystem Vendor ID (SVID) — RO. This value may be loaded automatically from the
NVM Word 0Bh upon power up or reset depending on the "Load Subsystem ID" bit field
in NVM word 0Ah with a default value of 0000h. This value is loadable from NVM word
location 0Bh.
