The assert and negate timings of the strobe signals can be modified as well as number of access
cycles.
• Read strobe (RD) in the basic bus interface
• Chip select assertion period extension cycles in the basic bus interface
• Data transfer acknowledge (DACK3 to DACK0) output for DMAC single address transfers
• Data transfer acknowledge (EDACK3 to EDACK0) output for EXDMAC single address

Area 0 includes on-chip ROM. All of area 0 is used as external address space in on-chip ROM
disabled extended mode, and the space excluding on-chip ROM is external address space in on-
chip ROM enabled extended mode.
When area 0 external address space is accessed, the CS0 signal can be output.
Either of the basic bus interface, byte control SRAM interface, or burst ROM interface can be
selected for area 0 by bit BSRM0 in BROMCR and bit BCSEL0 in SRAMCR. Table 9.7 shows
the external interface of area 0.
