void MA_Init_SCB( void ) 
/*
**---------------------------------------------------------------------------
**
**  Abstract:
**      Initialises the SCB module. Only sets those registers with  
**      values not equal to the power-on reset values. 
**
**      If the PLL shall be used this function only sets the PLL registers.
**      Changes to the PLLCFG registers will not take effect until a 
**      correct PLL feed sequence has been given into the PLLFEED register.
**      This must be done after the PLOCK bit is asserted. If PLL interrupt 
**      is enabled the feed sequence is done by MA_IntHandlerPLL_SCB().
**
**  Parameters:
**      None
**
**  Returns:
**      None
