/** @defgroup CSL_CHIP_API CHIP 
 *
 *  @section Introduction 
 *  
 * @subsection xxx Overview
 *  This module deals with all System On Chip (SOC) configurations. It consists
 *  of Configuration Registers specific for the chip. Following are the Registers
 *  associated with the CHIP module:   \n 
 *
 *      (1) Addressing Mode Register - This register specifies the addressing 
 *          mode for the registers which can perform linear or circular addressing, 
 *          also contain sizes for circular addressing  \n
 *          
 *      (2) Control Status Register - This register contains the control and status
 *          bits. This register is used to control the mode of cache. This is also 
 *          used to enable or disable all the interrupts except reset and 
 *          non maskable interrupt. \n
 *
 *      (3) Interrupt Flag Register - This register contains the status of 
 *          INT4-INT15 and NMI interrupt. Each corresponding bit in the IFR is set 
 *          to 1 when that interrupt occurs; otherwise, the bits are cleared to 0. \n
 *
 *      (4) Interrupt Set Register - This register allows user to manually set the
 *          maskable interrupts (INT4-INT15) in the interrupt flag register (IFR).
 *          Writing a 1 to any of the bits in ISR causes the corresponding interrupt 
 *          flag to be set in IFR. \n
 *
 *      (5) Interrupt Clear Register - This register allows user to manually clear
 *          the maskable interrupts (INT15-INT4) in the interrupt flag register 
 *          (IFR). Writing a 1 to any of the bits in ICR causes the corresponding 
 *          interrupt flag to be cleared in IFR. \n
 *
 *      (6) Interrupt Enable Register - This register enables and disables individual
 *          interrupts and this not accessible in User mode. \n
 *
 *      (7) Interrupt Service Table Pointer Register - This register is used to
 *          locate the interrupt service routine (ISR). \n
 *
 *      (8) Interrupt Return Pointer Register - This register contains the return
 *          pointer that directs the CPU to the proper location to continue program
 *          execution after processing a maskable interrupt. \n
 *
 *      (9) Nonmaskable Interrupt (NMI) Return Pointer Register - This register
 *          contains the return pointer that directs the CPU to the proper location 
 *          to continue program execution after processing of a non-maskable 
 *          interrupt (NMI). \n
 *
 *      (10)Exception Return Pointer Register - This register contains the return
 *          pointer that directs the CPU to the proper location to continue program
 *          execution after processing of a exception. \n
 *
 *      (11)Time Stamp Counter Registers - The CPU contains a free running 64-bit
 *          counter that advances each CPU clock after counting is enabled. The counter
 *          is accessed using two 32-bit read-only control registers, Time Stamp Counter
 *          Registers - Low (TSCL) and Time Stamp Counter Registers - High (TSCH). The
 *          counter is enabled by writing to TSCL. The value written is ignored. Once
 *          enabled, counting cannot be disabled under program control. Counting is
 *          disabled in the following cases:
 *                  a.  After exiting the reset state.
 *                  b.  When the CPU is fully powered down. \n
 *
 *      (12)Analysis Return Pointer \n
 *
 *      (13)SPLOOP Inner Loop Count Register - The SPLOOP or SPLOOPD instructions
 *          use the SPLOOP inner loop count register (ILC), as the count of the number
 *          of iterations left to perform. The ILC content is decremented at each stage
 *          boundary until the ILC content reaches 0. \n
 *
 *      (14)SPLOOP Reload Inner Loop Count Register - Predicated SPLOOP or 
 *          SPLOOPD instructions used in conjunction with a SPMASKR or SPKERNELR 
 *          instruction use the SPLOOP reload inner loop count register (RILC), as 
 *          the iteration count value to be written to the SPLOOP inner loop count 
 *          register (ILC) in the cycle before the reload operation begins. \n
 *
 *      (15)Restricted Entry Point Address Register - This register is used by the
 *          SWENR instruction as the target of the change of control when an SWENR
 *          instruction is issued. The contents of REP should be preinitialized by the
 *          processor in Supervisor mode before any SWENR instruction is issued.  \n
 *
 *      (16)E1 Phase Program Counter - This register contains the 32-bit address of the 
 *          fetch packet in the E1 pipeline phase. \n
 *
 *      (17)DSP Core Number Register - This register provides an identifier to shared 
 *          resources in the system which identifies which CPU is accessing those
 *          resources. The contents of this register are set to a specific value at reset. \n
 *
 *      (18)Saturation Status Register - This register provides saturation flags for
 *          each functional unit, making it possible for the program to distinguish
 *          between saturations caused by different instructions in the same execute 
 *          packet. \n
 *
 *      (19)GMPY Polynomial.A Side Register - The GMPY instruction uses the 32-bit
 *          polynomial in the GMPY polynomial-A side register (GPLYA), when the
 *          instruction is executed on the M1 unit. \n
 *
 *      (20)GMPY Polynomial.B Side Register - The GMPY instruction uses the 32-bit
 *          polynomial in the GMPY polynomial-B side register (GPLYB), when the 
 *          instruction is executed on the M2 unit. \n
 *
 *      (21)Galois Field Polynomial Generator Function Register - This register
 *          controls the field size and the Galois field polynomial generator of the
 *          Galois field multiply hardware. \n
 *
 *      (22)Debug Interrupt Enable Register - This register is used to designate 
 *          which interrupts and exceptions are treated as high priority interrupts
 *          when operating in real-time emulation mode. \n
 *
 *      (23)Task State Register - This register contains all of the status bits that
 *          determine or indicate the current execution environment. TSR is saved in the
 *          event of an interrupt or exception to the ITSR or NTSR, respectively. \n
 *
 *      (24)Interrupt Task State Register - This register is used to store the
 *          contents of the task state register (TSR) in the event of an interrupt. \n
 *
 *      (25)NMI/Exception Task State Register - This register is used to store
 *          the contents of the task state register (TSR) and the conditions under 
 *          which an exception occurred in the event of a nonmaskable interrupt (NMI) or 
 *          an exception. \n
 *
 *      (26)Exception Flag Register - This register contains bits that indicate
 *          which exceptions have been detected. Clearing the EFR bits is done by
 *          writing a 1 to the corresponding bit position in the exception clear
 *          register (ECR). \n
 *
 *      (27)Exception Clear Register - This register is used to clear individual
 *          bits in the exception flag register (EFR). Writing a 1 to any bit in ECR
 *          clears the corresponding bit in EFR. \n
 *
 *      (28)Internal Exception Report Register - This register contains flags that
 *          indicate the cause of the internal exception. \n
