In mode 3 (single-chip mode), this pin can be used for general-purpose input or output.
Reset: In the single-chip mode (mode 3), a reset initializes all pins of port 7 to the general-purpose
input state with the MOS pull-ups off. In the expanded modes (modes 1 and 2), P7
to P7
are
0
3
initialized as input port pins, and P7
to P7
are initialized to their bus control functions.

Hardware Standby Mode: All pins are placed in the high-impedance state with the MOS pull-ups
off.
Software Standby Mode: All pins remain in their previous state. For RD, WR, and AS this means
the high output state.
Figures 5-14 to 5-18 show schematic diagrams of port 7.
