Bits 31-16 are Status register and bits 15-0 are Command register. Reads to Status register behave
normally. Bits in Status register are cleared if the corresponding write data bits are '1' in a write
operation.
Bits 15-0 are Command register. When 00
H
is written to this register, the device is logically
disconnected from the PCI bus for all accesses except configuration accesses. The power up value of
Command register is 00
H.
Bit 31 DPE Detected Parity Error R/W_clr
1 = A parity error is detected.
0 = No parity error is detected.
Bit 30 SSE Signaled System Error
Not implemented. Read as 0.
Bits 29-28 Master Aborted, Target Aborted
Not implemented. Read as 0.
Bit 27 STA Signaled Target Abort R/W_clr
1 = Target Abort is signalled.
0 = Target Abort is not signalled.
Bits 26-25 DEVSEL Timing Read_only
01 = Medium DEVSEL# timing.
Bits 24 PERR# Asserted
Not implemented. Read as 0.
Bit 23 FBT Fast Back-to-back Transaction Read_only
0 = Unable to accept fast back-to-back transaction.
Bit 22 UDF User Definable Features Read_only
0 = Unable to support User Definable Features.
Bit 21 66M 66 MHz Function Read_only
0 = Support 33 MHz only.
