PRELIMINARY DATA SHEET v3.1
I/O WINDOW MAPPING REGISTERS
7.4
System I/O Map 0–1 End Address Low
There are two separate System I/O Map End Address Low registers, each with identical fields. These reg-
isters are located at the following indexes:
Index
Ah
Eh
System I/O Map End Address Low
System I/O Map 0 End Address Low
System I/O Map 1 End Address Low
Bits 7:0 — End Address 7:0
This register contains the least-significant byte of the address that specifies the termination of the
I/O space within the corresponding I/O map. I/O accesses that are equal or below this address
and equal or above the corresponding System I/O Map Start Address will be mapped into the I/O
space of the corresponding PC Card.
The most-significant byte is located in the
System I/O Map 0–1 End Address High
register (see
page
51
).
7.5
System I/O Map 0–1 End Address High
There are two separate System I/O Map End Address High registers, each with identical fields. These
registers are located at the following indexes:
Index
Bh
Fh
System I/O Map End Address High
System I/O Map 0 End Address High
System I/O Map 1 End Address High
Bits 15:8 — End Address 15:8
This register contains the most-significant byte of the End Address. See the description of the End
Address field associated with bits 7:0 of the
System I/O Map 0–1 End Address Low
register (see
page
51
).
