Hardware
With this instruction, 8-digit BCD set values are read from a digital switch.
DSW(––) utilizes 5 output bits and 8 input bits. Connect the digital switch and the
Input and Output Units as shown in the diagram below. Output point 5 will be
turned ON when one round of data is read, but there is no need to connect output
point 5 unless required for the application.
