Overview
The TKY instruction assigns a 4- or 8-digit value to a word element through 10 consecutive bit elements
and drives the corresponding bit elements to act.

Function
Ten consecutive bit variable units (for example, X input ports) are designated to represent the 0 to 9 keys in
decimal format. When key press actions are initiated (status: ON), 4-digit decimal values in the range 0 to
9999 can be input based on the action sequence. If the 32-bit instruction is used, 8-digit decimal values in
the range 0 to 99,999,999 can be input.
