... R8A66151SP 24-BIT I/O EXPANDER DESCRIPTION R8A66151 is a semiconductor integrated circuit which has 24-bit shift register function to execute serial in - parallel out conversion and parallel in - serial out conversion. Built in two shift registers for serial in - parallel out and parallel in - serial out are constructed independently, This IC is able to read serial input data into a shift register while output the serial data converting from the parallel data input ...

... R8A66151SP DESCRIPTION OF OPERATION (1) When power ON, the status of DO and D1~D24 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~D24 terminals is loaded on shift register 1. (3) Synchronous to the negative edge of CLK, 24-bit loaded data is serial output from the DO terminal. ...
