2-2-2 HEXADECIMAL KEY INPUT – HKY(––)
This instruction inputs 8 digits in hexadecimal from a hexadecimal keyboard. It
utilizes 5 output bits and 4 input bits.
Hardware Prepare the hexadecimal keyboard, and connect the 0 to F numeric key
switches, as shown below, to input points 0 through 3 and output points 0
through 3. Output point 4 will be turned ON while any key is being pressed,
but there is no need to connect it.
The inputs can be connected to the input terminals on the CPU Unit or a DC
Input Unit with 8 or more input points and the outputs can be connected from
a Transistor Output Unit with 8 points or more.
