n externally extended mode, all of area 1 is external address space. In on-chip ROM enabled
extended mode, the space excluding on-chip ROM is external address space.
When area 1 external address space is accessed, the CS1 signal can be output.
Either of the basic bus interface, byte control SRAM, or burst ROM interface can be selected for
area 1 by bit BSRM1 in BROMCR and bit BCSEL1 in SRAMCR. Table 8.8 shows the external
interface of area 1.
Table 8.8

In externally extended mode, all of area 2 is external address space.
When area 2 external address space is accessed, the CS2 signal can be output.
Either the basic bus interface or byte control SRAM interface can be selected for area 2 by bit
BCSEL2 in SRAMCR. Table 8.9 shows the external interface of area 2.
