Notes :
1. This timing illustrates bus cycle length. Read cycle and write cycle may be occur consecutively.
2. Address bus and chip-select signal may be output longer depending on CPU status such as an
instruction queue buffer.
3. When accessing the same external space (same CS space) consecutively, the chip select may be output
consecutively.
