Section 12 Bus State Controller (BSC)
12.5.2
Basic Timing: For access to a normal space, this LSI uses strobe signal output in consideration of
the fact that mainly static RAM will be directly connected. When using SRAM with a byte-
selection pin, see section 12.5.7, Byte-Selection SRAM Interface. Figure 12.3 shows the basic
timings of normal space access. A no-wait normal access is completed in two cycles. The BS
signal is asserted for one cycle to indicate the start of a bus cycle.
There is no access size specification when reading. The correct access start address is output in the
least significant bit of the address, but since there is no access size specification, 32 bits are always
