Basic I/O Unit Instructions
Section 3-23
Note
TKY(211) does not require a system word, unlike other I/O instructions such
as HKY(212).
Operand Specifications
Description
TKY(211) reads numeric data from input word I, which is allocated to a ten-
key keypad connected to an Input Unit, and stores up to 8 digits of BCD data
in register words D
1
and D
1
+1. In addition, each time that a key is pressed,
the corresponding bit in D
2
(0 to 9) will be turned ON and remains ON until
another key is pressed. Bit 10 of D
2
will be ON while any key is being pressed
and OFF when no key is being pressed.
The two-word register in D
1
and D
1
+1 operates as an 8-digit shift register.
When a key is pressed on the ten-key keypad, the corresponding BCD digit is
