Function
PORT1 consists of the two 8-bit bidirectional I/O ports P1L
and P1H. It is bit-wise programmable for input or output via
direction bits. For a pin configured as input, the output driver
is put into high-impedance state. 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.
The following PORT1 pins also serve for alternate functions:
