Data is input and output to and from

each pin by reading and writing to

and from each corresponding bit

(except for P85)

0 : “L” level data

1 : “H” level data

Note 1: Since P70 and P71 are N-channel open drain ports, the data is high-impedance.

Note 2: In memory expansion and microprocessor mode, the contents of

corresponding port Pi register of pins A0 to A19, D0 to D15, CS0 to CS3,

RD, WRL/WR, WRH/BHE, ALE, RDY, HOLD, HLDA and BCLK cannot

be modified.
