# 2.131.59 USART_LIN_CALLBACK Typedef

## C

    /* USART LIN mode */
    typedef void (* USART_LIN_CALLBACK)(uintptr_t context );

## Summary

Defines the data type and function signature for the USART LIN peripheral callback function.

## Description

This data type defines the function signature for the USART LIN peripheral callback function. The USART peripheral will call back the client's function with this signature when the USART LIN event has occurred.

## Precondition

USARTx_Initialize must have been called for the given USART peripheral instance. Callback must have been registered using USARTx_LINIdCallbackRegister, USARTx_LINTcCallbackRegister or USARTx_LINBreakCallbackRegister routines.

## Parameters

Param | Description
--- | ---
context | Allows the caller to provide a context value (usually a pointer to the callers context for multiple clients).

## Returns

None.

## Example

    uint8_t txBuffer[10];
    uint8_t nTxBytes = 0;
    void LIN_DataTransferComplete_Callback_Handler( uintptr_t context)
    {
        LINDataTransferComplete = true;
    }
    USART0_Initialize();
    USART0_LINTcCallbackRegister(LIN_DataTransferComplete_Callback_Handler, (uintptr_t)NULL);
    USART0_Write(txBuffer, nTxBytes);

## Remarks

None.
