Area 5 includes the on-chip RAM and access prohibited spaces. In external extended mode, area
5, other than the on-chip RAM and access prohibited spaces, is external address space. Note that
the on-chip RAM is enabled when the RAME bit in SYSCR are set to 1. If the RAME bit in
SYSCR is cleared to 0, the on-chip RAM is disabled and the corresponding addresses are an
external address space. For details, see section 3, MCU Operating Modes.
When area 5 external address space is accessed, the CS5 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 5 by the MPXE5 bit in MPXCR and the BCSEL5 bit in
SRAMCR. Table 8.12 shows the external interface of area 5.
