PORT0 consists of the two 8-bit bidirectional I/O ports P0L
and P0H. Each pin can be programmed for input (output
driver in high-impedance state) or output.
In case of an external bus configuration, PORT0 serves as
the address (A) and address/data (AD) bus in multiplexed
bus modes and as the data (D) bus in demultiplexed bus
modes.
Demultiplexed bus modes:
8-bit data bus: P0H = I/O, P0L = D7 - D0
16-bit data bus: P0H = D15 - D8, P0L = D7 - D0
Multiplexed bus modes:
8-bit data bus: P0H = A15 - A8, P0L = AD7 - AD0
16-bit data bus: P0H = AD15 - AD8, P0L = AD7 - AD0
Note: At the end of an external reset (EA = 0) PORT0 also
may input configuration values.
