IOBASE1 – I/O Base Address Register – Device #1
Address Offset:
1Ch
Default Value:
F0h
Access:
Read/Write, Read Only
Size:
8 bits
This register controls the hosts to AGP I/O access routing based on the following formula:
IO_BASE=< address =<IO_LIMIT
Only the upper 4 bits are programmable. For the purpose of address decode address bits A[11:0] are
treated as 0. Thus the bottom of the defined I/O address range will be aligned to a 4-KB boundary.
Bit
Description
7:4
I/O Address Base. Corresponds to A[15:12] of the I/O address. Default=Fh
3:0
Reserved

IOLIMIT1 – I/O Limit Address Register – Device #1
Address Offset:
1Dh
Default Value:
00h
Access:
Read/Write, Read Only
Size:
8 bits
This register controls the hosts to AGP I/O access routing based on the following formula:
IO_BASE=< address =<IO_LIMIT
Only the upper 4 bits are programmable. For the purpose of address decode address bits A[11:0] are
assumed to be FFFh. Thus, the top of the defined I/O address range will be at the top of a 4-KB aligned
address block.
Bit
Description
7:4
I/O Address Limit. Corresponds to A[15:12] of the I/O address. Default=0h
3:0
Reserved (Only 16-bit addressing supported)
