F00/FID Device ID Register
The register F00/FID specifies the vendor ID and the particular device ID in the W89C840AF.
Bit
Attribute
Bit name
Description
31:16
R
DID
Device ID. Loaded from EEPROM after hardware reset de-asserted.
15:0
R
VID
VendorID. Loaded from EEPROM after hardware reset de-asserted.
F04/FCS Command and Status Register (Offset + 04H)
Value after Hard-Reset: 02900000H
The F04/FCS comprises two parts, the one is the command register (FCS[15:0]) which provides the control
of 840 PCI activity, and the other is the status register (FCS[31:16]) which shows the status information of PCI
event.
Writing 00h to the command registers will put W89C840AF logically isolated from
all PCI access except
configuration access.
Writing 1 to the bits of the status register will clear them; writing 0 has no effect.

R/W
DPE
Detected Parity Error.
The DPE will be set if a parity error is detected by W89C840AF
even the parity error response bit of F04/FCS(bit 6) is disabled.
30
R/W
SSE
Signaled System Error.
The SSE will be set if W89C840AF assert SERRB.
