* Name: stmpe11_tempinterrupt
*
* Description:
* Configure the temperature sensor to sample the temperature periodically.
* Set the temperature threshold to generate an interrupt and notify
* to the client using the provide callback function pointer.
*
* Input Parameters:
* handle - The handle previously returned by stmpe11_instantiate
* threshold - The threshold temperature value
* direction - True: Generate an interrupt if the temperate exceeds the
* threshold value; False: Generate an interrupt if the
* temperature falls below the threshold value.
* callback - The client callback function that will be called when
* the termperature crosses the threshold.
*
* Returned Value:
* Zero is returned on success. Otherwise, a negated errno value is returned to indicate
* the nature of the failure.
