PCI Configuration Registers

4-5

Version 3.3

Copyright © 1998–2003 by LSI Logic Corporation. All rights reserved.

Registers: 0x06–0x07

Status
Read/Write

Reads to this register behave normally. Writes are slightly different in that
bits can be cleared, but not set. A bit is cleared whenever the register is
written, and the data in the corresponding bit location is a one. For
instance, to clear bit 15 and not affect any other bits, write the value
0x8000 to the register.

DPE

Detected Parity Error (from Slave)

15

This bit is set by the LSI53C896 whenever it detects a data
parity error, even if data parity error handling is disabled.

SSE

Signaled System Error

14

This bit is set whenever the device asserts the SERR/
signal.

RMA

Received Master Abort (from Master)

13

A master device should set this bit whenever its
transaction (except for Special Cycle) is terminated with
Master Abort.

RTA

Received Target Abort (from Master)

12

A master device should set this bit whenever its
transaction is terminated by target abort.
