SIEMENS C511/C513 STARTER KIT
--------------------------------------------------------------------------------
PROGRAM 	ssc_led
--------------------------------------------------------------------------------
MODUL NAME	ssc_led.c
--------------------------------------------------------------------------------
DESCRIPTION	This program is an example for a SSC application, running
		on a C511/C513 microcontroller. The controller is configured
		to run in master mode.
		Data are sent to the LED display via SSC interface.
--------------------------------------------------------------------------------
FUNCTIONS	void main(void) ;
		void Wait();
		void InitUsart(void);
--------------------------------------------------------------------------------
NOTE		No connection to the SSC slave controller in socket U5 can be
		established with the Starter Kit board, because Tasking
		CrossView uses INT0 interrupt which is also used on the
		miniCON-513 as PVCC# signal.
--------------------------------------------------------------------------------
ENVIRONMENT	The program runs on the C511/C513 Starter Kit board miniCON-513.
		The program is dedicated for the SAB-C513A-RN microcontroller
		in socket U1.
--------------------------------------------------------------------------------
VERSION 	V1.0
