/** @file
 @brief Chipset API H Template

 This is a header template for Chipset API work. This template should not be
 used as a normal code template because the location of where the API is
 documented is different in normal coding style! Doxygen commenting style tries
 to be similar what Symbian is using for their kernel side development.

 You can define here also the scope of the whole API see below, or you can
 define the scope separately before the class or even before the function if
 that is needed.
