4-13.General-purpose I/O PORT
The C-875 is provided with a general-purpose I/O with 4 input points (IN0 to IN3 input signals) and
4 output points (OUT0 to OUT3 output signals). The user can freely use this general-purpose I/O.
These signals are active low.
When each of them is in the active state, the LED on the board come on.
(1) Input port
The input port consists of an input data division and an output data division as shown below.
The external input (IN0 to IN3) states are read into the input data division.
The output data division reads the current output port state (data previously output to the output port).
* Each of these bits becomes 1 in the active state.

(2) Output data port
The output port consists of the following bits and outputs the contents of the 4 low-order bits to the
outside (OUT0 to OUT3).
