7.3
A strobe signal is output by ordinary space accesses to provide primarily for SRAM or ROM
direct connections.
7.3.1
Figure 7.3 shows the basic timing of ordinary space accesses. Ordinary access bus cycles are
performed in 2 states.
During a read, irrespective of operand size, all bits in the data bus width for the access space
(address) are fetched by the LSI on RD, using the required byte locations.
During a write, the following signals are associated with transfer of these actual byte locations:
WRH (bits 15–8) and WRL (bits 7–0).
