# 1.1.1.4.11 DRV_PLC_PHY_ExternalInterruptHandler Function

## C

    void DRV_PLC_PHY_ExternalInterruptHandler (
        const PIO_PIN pin,
        const uintptr_t context
    );

## Summary

Allows application to register callback for PLC Interrupt pin.

## Description

This function allows a client to register a callback function to handle PLC interrupt.

## Precondition

DRV_PLC_PHY_Initialize must have been called before calling this function.

## Parameters

Param | Description
--- | ---
pin | PIO pin where interrupt source is connected.
context | Pointer to parameters to be passed to Handler function.

## Returns

None.

## Example

    // Initialize PLC Driver Instance
    sysObj.drvPLC = DRV_PLC_PHY_Initialize(DRV_PLC_PHY_INDEX, (SYS_MODULE_INIT *)&drvPlcPhyInitData);
    // Register Callback function to handle PLC interruption
    PIO_PinInterruptCallbackRegister(DRV_PLC_EXT_INT_PIN, DRV_PLC_PHY_ExternalInterruptHandler, sysObj.drvPLC);

## Remarks

See `plib_pio.h` for more details.
