6.3.1
The external address space is divided into areas 0 to 7. Each area has a size of 128 kbytes in the 1-
Mbyte modes, or 2 Mbytes in the 16-Mbyte modes. Figure 6.2 shows a general view of the
memory map.
Chip select signals (
area are selected in ABWCR, ASTCR, WCRH, and WCRL.
In 16-Mbyte mode, the area division units can be selected with the RDEA bit in BCR.
