Bit 4
I/O Window 1 Size
When bit 5 below is
0
, this bit determines the size of the data path to I/O Window 1. When bit 5 is
1
, this bit is ignored.
Bit 5
Auto-Size I/O Window 1
This bit determines the width of the data path to I/O Window 1. Note that when this bit is
1
, the
-IOIS16 signal (see
Table 2 on page 20
) determines the window size. This bit must be set for
proper ATA mode operation (see
ATA Mode Operation
on page 88
).
Bit 7
Timing Register Select 1
This bit determines the access timing specification for I/O Window 1 (see
Setup Timing 0
1
on
page 84
).

System I/O Map 0
1 Start Address Low
There are two separate System I/O Map Start Address Low registers, each with identical fields.
These registers are located at the following indexes:
Index
8h
Ch
System I/O Map Start Address Low
System I/O Map 0 Start Address Low
System I/O Map 1 Start Address Low
0
8-bit data path to I/O Window 1.
1
16-bit data path to I/O Window 1.
0
I/O Window 1 Size (see bit 4) determines the data path to I/O Window 1.
1
The data path to I/O Window 1 will be determined based on -IOIS16 returned by the card.
0
Accesses made with timing specified in Timing Set 0.
