Function
PORT0 consists of the two 8-bit bidirectional
I/O ports P0L and P0H. It is bitwise
programmable for input or output via direction
bits. For a pin configured as input, the output
driver is put into high-impedance.
In case of an external bus configuration,
PORT0 serves as the address (A) and
address/data (AD) bus in demultiplexed bus
modes.

PORT1 consists of the two 8-bit bidirectional
I/O ports P1L and P1H. It is bitwise
programmable for input or output via direction
bits. For a pin configured as input, the output
driver is put into high-impedance.
PORT1 is used as the 16-bit address bus (A)
in demultiplexed bus modes and also after
switching from a demultiplexed bus mode to a
multiplexed bus mode (see Chapter 8.3).
