1. When D is used as a word device, n = 1 ~ 4. Errors will occur if n = 0 or n > 4.

2. When

n = 4, the decoded data is 2

4

= 16 bits.

3.

When X20 goes from OFF to ON, the data in D10 (b2 to b0) will be decoded and stored in

D20 (b7 to b0). The unused bits in D20 (b15 to b8) will be set to 0.

4.

The lower 3 bits of D10 are decoded and stored in the lower 8 bits of D20. The higher 8 bits

of D20 are all 0.

5.

After the execution is completed, X20 is turned OFF. The decoded results or outputs will

retain their operation.
