Operands:

S: Source device to be decoded

D: Device for storing the result

n: Number of consecutive

bits of S

Explanation:

1.The instruction decodes the lower “n” bits of S and stores the result of “2n” bits in D.

2.This instruction is generally used in pulse execution mode (DECOP).

3.When operand D is a bit device, n = 1~8, when operand D is a word device, n = 1~4

Program Example 1:

1.When D is used as a bit device, n = 1 ~ 8. Errors will occur if n = 0 or n > 8.

2.If n = 8, the decoded data is 28= 256 bits data.

3.When X20 goes from OFF to ON, the data of X0~X2 will be decoded to M100~M107.

4.If the source data is 3, M103 (third bit from M100) = ON.

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