7. Serial Interface Structure
The serial interface consists of a control circuit, shift registers, and I/O ports.
Note: The SI pin can also be used as I/O port 5 (P5-1).
Note: The contents of the shift registers are loaded to data memory as the data and serial input data. Therefore,
the data set as serial output data and the serial input data do not match.
Note: The serial input pins all incorporate Schmitt trigger circuits.
