System Memory Map 0–4 End Address Low
There are five separate System Memory Map End Address Low registers, each with identical
fields. These registers are located at the following indexes:
Bits 7:0 — End Address 19:12
This register contains the least-significant byte of the address that specifies where in the memory
space the corresponding memory map will end. Memory accesses that are equal or below this
address and equal or above the corresponding System Memory Map Start Address will be mapped
into the memory space of the corresponding PC Card.
The most-significant four bits are located in the System Memory Map 0–4 End Address High
register (see
