Bits
Access Default Description
31:9
0x0
Reserved
9
RO
0x0
Fast back to back enable
This 1 bit field is fixed to “0” because the bridge doesn’t support fast
back to back transaction.
8
RW
0x0
CSERR enable
This 1 bit field is used for enabling nCSERR pin interrupt.
7
RW
0x0
Wait cycle control (No connection to actual block)
This 1 bit field is fixed to “0” because the bridge doesn’t support this
function.
6
RW
0x1
Parity error response
This 1 bit field is used for enabling nCPERR pin interrupt.
5
RO
0x0
VGA pallet snoop enable
This 1 bit field is fixed to logic 0 because the bridge doesn’t support
this functionality.
4
RO
0x0
Memory write invalidate enable
This 1 bit field is used for enabling MWI and MRL command.
3
RO
0x0
Special cycle monitoring enable
This 1 bit field is fixed to logic 0 because the bridge doesn’t support
this functionality.
2
RO
0x1
Bus mastering enable
This 1 bit field is fixed to logic 1 because the bridge always supports
the master functionality.
1
RO
0x1
Memory access enable
This 1 bit field is fixed to logic 1 because the bridge always supports
the memory area accessing.
