OE is an output enabling port, which generally exists on data latch chip used as a single chip microcomputer.

WR and RD are read-write control ports of off-chip data storage, which generally exist in P3 port of single chip microcomputer. When the operating instruction MOVX of the off-chip data memory is executed, these two signals are automatically generated respectively.
