(4) Address area size specification
Chip Select/Wait Control Registers
wait states for each address area (CS0 to CS3 and others) are set in their respective chip
select/wait control registers, B0CS to B3CS and BEXCS.
Example: To set the area size for CS0 to 128 Kbytes:
Figure 3.6.5 lists the chip select/wait control registers.
The master enable/disable, chip select output waveform, data bus width and number of

register combinations. When setting an area size using a combination indicated by Δ,
set the start address mask register in the desired steps starting from 000000H.

Any of these addresses may be set as the start address.
This is not an integer multiple of the desired area size
setting. Hence, none of these addresses can be set as the
start address.
