2-2 Advanced I/O Instructions (CQM1 Only)
Advanced I/O instructions enable control, with a single instruction, of previ-
ously complex operations involving external I/O devices (digital switches, 7-
segment displays, etc.). This section introduces advanced I/O instructions,
which are also covered at the end of SECTION 5 Instruction Set.
There are four advanced I/O instructions, as shown in the following table. All
of these are expansion instructions and must be assigned to function codes
before they can be used.
2-2-1 TEN-KEY INPUT – TKY(18)
This instruction inputs 8 digits in BCD from a 10-key keypad and uses 10 input
points.
Hardware Prepare a 10-key keypad, and connect it so that the switches for numeric keys
0 through 9 are input to points 0 through 9 as shown in the following diagram.
Either the input terminals on the CPU Unit or the inputs on a DC Input Unit
with 16 or more input points can be used.
