+ * 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:
+ * 1 : Result of function, 0 on success, otherwise error code
+ * 2 : Unknown, for now assume AppID of the process which sent these parameters
+ * 3 : Unknown, for now assume Signal type

+ * 5 : Value
+ * 6 : Handle from the source process which set the parameters, likely used for shared memory
+ * 7 : Size
