Note:
Since the CPU accesses the internal area to read data from a port, the control signals of external
pins such as RD and CS are not enabled. Therefore, the above waveform diagram should be
regarded as depicting internal operation. Please also note that the timing and AC characteristics
of port input/output shown above are typical representation. For details, contact your local
Toshiba sales representative.
