11.3 Control Operation Instructions
■Input data
■Block memory
This instruction outputs the minimum value out of input values E1 to En.
■Low selector processing
The minimum value out of input values E1 to En is stored in the output value (BW).
In addition, the BB output selection (BB1 to BB16) corresponding to the minimum value is set to 1.
The correspondence between input values 1 (E1) to 16 (E16) and BB output selections (BB1 to BB16) is shown below.

Bit to be set to 1 at the minimum value BB16 BB15 BB14 to BB2 BB1
Condition Processing
Two or more minimum values exist. The bits corresponding to the minimum values are all set to 1.
Only one input Only input value 1 (E1) is used as the input value. • The input value 1 (E1) is stored in the output value (BW).
• BB output selection BB1 is set to 1.
• BB output selections BB2 to BB16 are set to 0.
Only one of input values 2 (E2) to 16 (E16) is used
as the input value.
A value out of input values 2 (E2) to 16 (E16) and the value of
input value 1 (E1) are used for data processing.
Error code Error content
