Note 1: This timing example shows bus cycle length. Read cycle and write cycle may be continued after this
Note 2: Address bus and chip select may get longer by a state of CPU such as an instruction queue buffer.
Note 3: When accessing same external area (same CS area) continuously, chip select may output
