Function
PORT0 consists of the two 8-bit bidirectional I/
O ports POL and POH. It is bitwise
programmable for input or output via direction
bits. It contains internal pull resistors.
For external memory access, PORT0 serves
as the data (D) bus in demultiplexed bus
modes.
Beside these functions, P0 serves for latching
in the start-up configuration during reset.
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. It contains internal pull resistors.
For external memory access PORT1 is used
as the 16-bit address bus (A) in demultiplexed
bus modes.
PORT4 is a 6-bit bidirectional I/O port. It is bit-
wise programmable for input or output via
direction bits. It contains internal pull resistors.
For external memory access Port4 can be
used to output the segment address lines:
P4.0 A16 : Least Significant Segment Address
Line
...
P4.5 A21: Most Significant Segment Address
Line
PORT6 is a 3-bit bidirectional I/O port. It is bit-
wise programmable for input or output via
direction bits. It contains internal pull resistors.
