Nothing is assigned.

In an attempt to write to this bit, write “0”. The value, if read, turns out to be

indeterminate.

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

corresponding port Pi direction 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.

Note 1: Set bit 2 of protect register (address 000A16) to “1” before rewriting to

the port P9 direction register.
