Operands:
S
: Starting input address (occupies 10 consecutive bits)
D

: Destination for storing key input
value
D
2
: Key input signal (occupies 11 consecutives bits)
Description:
1. This instruction specifies ten external inputs with
S
and these ten external inputs are identified
as decimal values of 0 to 9. These ten external input devices are connected to ten keys. When
each key is pressed, the decimal value for that key from 0 to 9,999 (max. 4 digits in 16-bit
instruction) or from 0 to 99,999,999 (max. 8 digits in 32-bit instruction) is stored in destination
D

.
D

is used to store the state of the current key number pressed.
2. For ELC-PC/PA/PH,
S
and
D
2
do not support E, F index registers
3. There is no limit on the number of times this instruction is used in the program, however only
one instruction is allowed to be executed at a time.
Program Example:
1. Specify ten input terminals beginning with X30 to connect the ten keys to. These keys are
numbered from 0 to 9. When X20=ON, the instruction is executed and it will store the BIN
value of the key pressed into D0 and set the associated bit (M10~M19). M0-M9 in this example
are used to store the condition of the key that has been pressed last.
