6-Bit Parallel-in Serial-out Shift-Register-PISO.

A 6-bit shift register with parallel input and serial output. The 6 logic sources at the top are for DATA SELECTION. The top logic source on the left ENABLES/DISABLES data input. The middle logic source on the left is the WRITE/SHIFT selector. Bottom logic source on the left is the CLOCK. To begin, clear register by setting CLOCK to LOW. To WRITE data, The WRITE/SHIFT is set low and the ENABLE/DISABLE is set HIGH. Input data with the 6 DATA SELECTION logic sources then CLOCK (set CLOCK to HIGH then LOW by pressing the CLOCK twice. At this point the selected data should be indicated by the six LED's. Set the ENABLE/DISABLE to low, the WRITE/SHIFT to high and then shift the data out of the register by continually setting CLOCK to HIGH then to LOW. Data will shift left to right until register clears.
