I/O Ports
(1) Outline of I/O ports
When a data register serving for control output is read, the data output from it as a control output is read regardless
of the value in the direction register. Note that, if a read-modify-write instruction (such as a bit set instruction) is
used to preset output data in the data register when changing its setting from input to output, the data read is
not the data register latched value but the input data from the pin.
Ports 0 to 4 and 6 are input/output ports which serve as inputs when the direction register value is “0” or as
outputs when the value is “1”.
Port 5 are input/output ports as other port when ADER is 00H.
