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 9.5.7, Byte-Selection SRAM Interface. Figure 9.3 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.
