# MIC_StopAutoSamplingAsync

## Syntax

  `#include <nitro/spi.h>`

      MICResult MIC_StopAutoSamplingAsync(
                  MICCallback		callback,
                  void*		arg );

## Arguments

callback | Specifies the pointer to the callback function. This callback is called from within the interrupt handler.
arg | Argument to pass to the callback function.

## Return Values

Returns the processing result as a `MICResult` enumerated type. Returns `MIC_RESULT_SUCCESS` if the asynchronous process starts normally, and some other value if the process fails for some reason.

## Description

Asynchronously stops microphone auto-sampling. The function issues a request to the ARM7 to stop auto-sampling and returns control to the caller without waiting for a response. You must use the `result` argument passed by the user callback function to get the ARM7 processing result. If this function fails, the asynchronous operation is not performed and the user callback function is not called.

This function will return `MIC_RESULT_INVALID_COMMAND` when the CODEC is running in CODEC-TWL mode, because auto-sampling cannot be run at an arbitrary frequency in CODEC-TWL mode.
