3.1.4.
VID
VENDOR IDENTIFICATION REGISTER
Address Offset:
Default Value:
Attribute:
00–01h
8086h
Read Only
The VID Register contains the vendor identification number. This 16-bit register combined with the Device
Identification Register uniquely identify any PCI device. Writes to this register have no effect.
Bit
Description
15:0
Vendor Identification Number
.
This is a 16-bit value assigned to Intel.
3.1.5.
DID
DEVICE IDENTIFICATION REGISTER
Address Offset:
Default Value:
Attribute:
02–03h
7100h
Read Only
This 16-bit register combined with the Vendor Identification register uniquely identifies any PCI device. Writes
to this register have no effect.
Bit
Description
15:0
Device Identification Number
.
This is a 16 bit value assigned to the MTXC.
3.1.6.
PCICMD
PCI COMMAND REGISTER
Address Offset:
Default:
Access:
04–05h
06h
Read/Write
This 16-bit register provides basic control over the MTXC’s ability to respond to PCI cycles. The PCICMD
Register in the MTXC enables and disables the assertion of SERR# and PCI master accesses to main
memory.
Bit
Description
15:10
Reserved
.
9
Fast Back-to-Back (FB2B). (Not implemented)
This bit is hardwired to 0.
8
SERR# Enable (SERRE)
.
(Not implemented)
This bit is hardwired to 0.
7
Address/Data Stepping
.
(Not implemented)
This bit is hardwired to 0.
6
Parity Error Enable (PERRE)
.
(Not implemented)
This bit is hardwired to 0.
5
Video Pallet Snooping (VPS)
.
(Not implemented)
This bit is hardwired to 0.
4
Memory Write and Invalidate Enable (MWIE)
.
(Not implemented)
This bit is hardwired to 0.
The MTXC will never use the Memory Write and Invalidate PCI command.
