SSP Low Power Mode -- g_lpm.p_api->enterLowPowerMode() missing

Hi, 

I'm currently working with S3A7-DK board using e2Studio 5.0.0.024 with SSP 1.1.0Alpha. 

On page 4.17 of the SSP UM, there is an example on how to enter sleep mode. After calling lowPowerCfg() function, the example shows to call enterLowPowerMode().

However, it seems that this function is not listed under !p_api!  ? Could it be missing ? 

Thanks.
