Card I/O Map 0–1 Offset Address Low
There are two separate Card I/O Map Offset Address Low registers, each with identical fields.
These registers are located at the following indexes:
Bits 7:1 — Offset Address 7:1
This register contains the least-significant byte of the quantity that will be added to the host I/O
address; this will determine the PC Card I/O map location where the I/O access will occur.
The most-significant byte is located in the Card I/O Map 0–1 Offset Address High register (see
