Bits 7:0 — Start 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 begin. Memory accesses that are equal or above this
address and equal or below the corresponding System Memory Map End 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 Start Address High
register (see
System Memory Map 0–4 Start Address High
There are five separate System Memory Map Start Address High registers, each with identical
fields. These registers are located at the following indexes:
Bits 3:0 — Start Address 23:20
This field contains the most-significant four bits of the Start Address. See the description of the
Start Address field associated with bits 7:0 of the System Memory Map 0–4 Start Address Low
register (see
