* APT_U::ReceiveParameter service function. This returns the current parameter data from NS state,

* not set again. This is called when the second Initialize event is triggered. It returns a signal

* type indicating why it was triggered.
|

* Inputs:
|
||||
* 1 : AppID
|
||||
* 2 : Parameter buffer size, max size is 0x1000
|

* Outputs:
|
