Section 6 Bus Controller (BSC)
Table 6.8
(3)
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 6.9 shows the external interface of area 2.
Table 6.9
(4)
In externally extended mode, all of area 3 is external address space.
When area 3 external address space is accessed, the CS3 signal can be output.
Either of the basic bus interface, byte control SRAM interface, or address/data multiplexed I/O
interface can be selected for area 3 by bit MPXE3 in MPXCR and bit BCSEL3 in SRAMCR.
Table 6.10 shows the external interface of area 3.
