... Also, parallel data I/O pins can be set to input mode or output mode by a bit. R8A66155 is useful in a wide range of applications, such as MCU (micro controller unit) I/O port extension and serial bus system data communication. Moreover, R8A66155 can be used as the anode common LED drive, too. ...

... R8A66155SP DESCRIPTION OF OPERATION (1) When power ON, the status of DO and D1~D16 terminals are not determined. These terminals are turn to high-impedance when "L" is input to the /S terminal. (2) By the negative edge of /CS, the status of D1~D16 terminals is loaded on shift register 1. (3) Synchronous to the negative edge of CLK, 16-bit loaded data is serial output from the DO terminal. ...
