[Valid for](../../../Shared/FeatureAvailability.md): CANoe DE • CANoe4SW DE

## Function Syntax

* `linSetWakeupCondition(dword numWakeupSignals); // form 1`
* `linSetWakeupCondition(dword numWakeupSignals, dword forgetWupsAfterMS); // form 2`

## Description

Determines the conditions under which the LIN hardware can be reactivated (leaves the sleep mode).

**Note:** When LIN hardware is not in master mode calling this function will have no effect.

## Parameters

* **numWakeupSignals**\
  This parameter specifies the number of wakeup signals, after that the LIN hardware is reactivated. If the value 0 is set, the LIN hardware will never leave the sleep mode.\
  Value range: 0..31\
  Default value: 1

* **forgetWupsAfterMS**\
  This parameter defines the time after that earlier wake-up signals are not any longer taken into account for the wake-up behavior.\
  Default value: 0

## Return Values

On success, a value unequal to zero, otherwise zero.

## Example

```plaintext theme={null}
// configure LIN hardware to wakeup after 3 wakeup signals
linSetWakeupCondition (3);
```
