;PwmCfg==========Configure PWM mode:
;C Function prototype:	char PwmCfg(char cCfg).
;Description of Function:	Select mode and clock source and prescaler.
 ; User interface: Set parameter1 to the required PWMCON register value.
;			Call PwmCfg.
;			Returns parameter1. 
;Robustness:	This function terminates any pulse generation in progress and 
;		restarts with the new settings.
;		Ensure PWPO in CFG842 selects required pins.
;Side effects:	None.
