The presettable shift register writes the serial interface serial out data and reads the serial interface serial

in data.

Relationship between Presettable Shift Register and Data Buffer

Serial interface serial data is output while being shifted sequentially the data from the MSB (bit b7) of the

presettable shift register.

During serial data input, data is shifted sequentially from the LSB (bit b0).
