Reserved. (by PCI SIG)

INTxDisable: Interrupt Disable
Controls the ability of the PCI Express port to generate INTx messages.
If this device does not generate interrupts then this bit is not implemented and

is RO.
If this device generates interrupts then this bit is RW and this bit disables the

device/function from asserting INTx#. A value of 0 enables the assertion of its

INTx# signal. A value of 1 disables the assertion of its INTx# signal.
1 = Legacy Interrupt mode is disabled
0 = Legacy Interrupt mode is enabled

FB2B: Fast Back-to-Back Enable
This bit controls whether or not the master can do fast back-to-back writes.

Since this device is strictly a target this bit is not implemented. This bit is

hardwired to 0. Writes to this bit position have no effect.

SERRE: SERR Message Enable
This bit is a global enable bit for this devices SERR messaging. This host bridge

will not implement SERR messaging. This bit is hardwired to 0. If SERR is used

for error generation, then this bit must be RW and enable/disable SERR

signaling.

IDSELWCC: IDSEL Stepping/Wait Cycle Control
Per PCI 2.3 specification this bit is hardwired to 0.

PERRE: Parity Error Response Enable
Parity error is not implemented in this host bridge. This bit is hardwired to 0.

VGAPSE: VGA palette snoop Enable
This host bridge does not implement this bit. This bit is hardwired to 0.

MWIEN: Memory Write and Invalidate Enable
This host bridge will never issue memory write and invalidate commands. This

bit is therefore hardwired to 0.

SCE: Special Cycle Enable
This host bridge does not implement this bit. This bit is hardwired to a 0.

BME: Bus Master Enable
This host bridge is always enabled as a master. This bit is hardwired to a 1.

MSE: Memory Space Enable
This host bridge always allows access to main memory. This bit is not

implemented and is hardwired to 1.

IOAE: Access Enable
This bit is not implemented in this host bridge and is hardwired to 0.
