Switching Bit I/O
The I/O which can be set in the input or output mode in bit units is called a bit I/O. P0E is a bit I/O port, which can be
set in the input or output mode in bit units by the register file shown below. When the mode is changed from input to output,
the P0E output latch contents are output to the port lines, as soon as the mode has been changed.
