Datasheet
8.0
I/O Window Mapping Registers
The I/O windows must never include 3E0h and 3E1h.
8.1
I/O Window Control
Bit 0
I/O Window 0 Size
When bit 1 below is
0
, this bit determines the size of the data path to I/O Window 0. When bit 1 is
1
, this bit is ignored.
Bit 1
Auto-Size I/O Window 0
This bit determines the data path to I/O Window 0. Note that when this bit is
1
, the -IOIS16 signal
(see
Table 2 on page 20
) determines the width of the data path to the card.
Bit 3
Timing Register Select 0
This bit determines the access timing specification for I/O Window 0 (see
Setup Timing 0
1
on
page 84
).
