Note 1 : These example timing charts indicate bus cycle length.
After this bus cycle sometimes come read and write cycles in succession.
Note 2 : The address bus and chip select may be extended depending on the CPU status
such as that of the instruction queue buffer.
Note 3 : This figure shows microcomputer internal state.
