9.6
A strobe signal is output in external space accesses to provide primarily for SRAM or ROM direct
connections.
9.6.1
External access bus cycles are performed in 2 states. Figure 9.3 shows the basic timing of external
space access.
During a read, irrespective of operand size, all bits (8 bits in this LSI) in the data bus width for the
access space (address) accessed by RD signal are fetched by the LSI.
During a write, the WRL (bits 7 to 0) signal indicates the byte location to be written.
