12h
1Ah
22h
2Ah
32h
System Memory Map 0 End Address Low
System Memory Map 1 End Address Low
System Memory Map 2 End Address Low
System Memory Map 3 End Address Low
System Memory Map 4 End Address Low
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 ends. Memory accesses that are equal to or below this
address and equal to or above the corresponding System Memory Map Start Address are 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.
