The following table shows the parameters of the "Decode" instruction:



You can select the data type of the instruction from the "???" drop-down list of the instruction box.

For additional information on valid data types, refer to "See also".

Example

The following example shows how the instruction works:



The following figure shows how the instruction works using concrete operand values:



If the "TagIn" operand has signal state "1", the instruction is executed. The instruction reads bit number "3" from the value of the operand "TagIn_Value" and sets the third bit to the value of the operand "TagOut_Value".

If no errors occur during the execution of the instruction, the output ENO has the signal state "1" and the output "TagOut" is set.

ENCO: Encode

Description

The instruction "Encode" is used to read the bit number of the lowest bit in the input value and output it to the output OUT.

The instruction "Encode" selects the least significant bit of the value at the IN input and writes its bit number to the tag in the output OUT.
