Fig. 13.3−1 Data input /output of SSI interface
For the data input / data output, 4 bytes are available which are transmitted to the
module or output by the module.
) Note!
Input and output data are lost when the supply voltage is
disconnected; they are not saved!
The input data can be used to control the outputs (I/O.0 and I/O.1) depending on
the encoder value.
