Chapter 6 Applied Instructions 4. You can use the 32-bit counter only when D 2 uses 32-bit instructions. Example 1. The four external inputs X0–X3 are connected to the four external outputs Y0–Y3 to form a 16-key keypad. When X10 is ON, the instruction stores the value that you enter as a binary value in D0, and stores the output signals in M0–M7. The function of SM691: If SM691 is ON, the 16-bit instruction takes 0–F as hexadecimal values. Numeric keys: 0 1 2 3 4 5 6 7 8 9 A B C D E F Kyes 6_ Overflowing 16 16 16 16 3 2 1 0 D0 If SM691 is OFF, the 16-bit instruction takes A–F as function keys. Numeric keys:
