### Interfaces

#### Inputs

| Name  | Data type | Value range | Initial value | Function     |
| ----- | --------- | ----------- | ------------- | ------------ |
| *xEn* | BOOL      |             |               | Store signal |
| *rIn* | REAL      |             |               | Input value  |

#### Outputs

| Name   | Data type | Value range | Initial value | Function     |
| ------ | --------- | ----------- | ------------- | ------------ |
| *rOut* | REAL      |             | 0             | Output value |

### Function description

#### Output value *rOut*

The current value at the input value *rIn* is stored on each rising edge at the input Store signal *xEn* and transferred directly to the output value *rOut* .\
As a result, the value of *rOut* can only change on a rising edge and does not change its value in all other situations.
