/***************************************************************************
Function: sInitController
Purpose:  Initialization of controller global registers and controller
	  structure.
Call:	  sInitController(CtlP,MudbacCtlP,AiopNum,
			  IRQNum,Frequency,PeriodicOnly)
	  CONTROLLER_T *CtlP; Ptr to controller structure
	  CONTROLLER_T *MudbacCtlP; Ptr to Mudbac controller structure
	  int AiopNum; Number of Aiops
	  int IRQNum; Interrupt Request number.  Can be any of the following:
			 0: Disable global interrupts
			 3: IRQ 3
			 4: IRQ 4
			 5: IRQ 5
			 9: IRQ 9
			 10: IRQ 10
			 11: IRQ 11
			 12: IRQ 12
			 15: IRQ 15
	  Byte_t Frequency: A flag identifying the frequency
		   of the periodic interrupt, can be any one of the following:
		      FREQ_DIS - periodic interrupt disabled
		      FREQ_137HZ - 137 Hertz
		      FREQ_69HZ - 69 Hertz
		      FREQ_34HZ - 34 Hertz
		      FREQ_17HZ - 17 Hertz
		      FREQ_9HZ - 9 Hertz
		      FREQ_4HZ - 4 Hertz
		   If IRQNum is set to 0 the Frequency parameter is
		   overidden, it is forced to a value of FREQ_DIS.
	  int PeriodicOnly: TRUE if all interrupts except the periodic
			       interrupt are to be blocked.
			    FALSE is both the periodic interrupt and
			       other channel interrupts are allowed.
			    If IRQNum is set to 0 the PeriodicOnly parameter is
			       overidden, it is forced to a value of FALSE.
Return:   int: Number of AIOPs on the controller, or CTLID_NULL if controller
	       initialization failed.

Comments:
	  If periodic interrupts are to be disabled but AIOP interrupts
	  are allowed, set Frequency to FREQ_DIS and PeriodicOnly to FALSE.

	  If interrupts are to be completely disabled set IRQNum to 0.

	  Setting Frequency to FREQ_DIS and PeriodicOnly to TRUE is an
	  invalid combination.

	  This function performs initialization of global interrupt modes,
	  but it does not actually enable global interrupts.  To enable
	  and disable global interrupts use functions sEnGlobalInt() and
	  sDisGlobalInt().  Enabling of global interrupts is normally not
	  done until all other initializations are complete.

	  Even if interrupts are globally enabled, they must also be
	  individually enabled for each channel that is to generate
	  interrupts.

Warnings: No range checking on any of the parameters is done.

	  No context switches are allowed while executing this function.

	  After this function all AIOPs on the controller are disabled,
	  they can be enabled with sEnAiop().
