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 */ #ifndef CSL_CHIP_H #define CSL_CHIP_H #ifdef __cplusplus extern "C" { #endif #include #include #if defined(_TMS320C6X) #include #endif #include /** @defgroup CSL_CHIP_ENUM CHIP Enumerated Data Types @ingroup CSL_CHIP_API */ /** @defgroup CSL_CHIP_FUNCTION CHIP Functions @ingroup CSL_CHIP_API */ /* CHIP global macro declarations */ /* CHIP global typedef declarations */ /** @addtogroup CSL_CHIP_ENUM @{ */ /** Enum for the CHIP registers */ typedef enum { /** Addressing Mode Register */ CSL_CHIP_AMR = 0, /** Control Status Register */ CSL_CHIP_CSR = 1, /** Interrupt Flag Register */ CSL_CHIP_IFR = 2, /** Interrupt Set Register */ CSL_CHIP_ISR = 2, /** Interrupt Clear Register */ CSL_CHIP_ICR = 3, /** Interrupt Enable Register */ CSL_CHIP_IER = 4, /** Interrupt Service Table Pointer Register */ CSL_CHIP_ISTP= 5, /** Interrupt Return Pointer Register */ CSL_CHIP_IRP= 6, /** Nonmaskable Interrupt (NMI) Return Pointer Register */ CSL_CHIP_NRP= 7, /** Exception Return Pointer Register */ CSL_CHIP_ERP= 7, /** Time Stamp Counter Register - Low */ CSL_CHIP_TSCL= 10, /** Time Stamp Counter Registers - High */ CSL_CHIP_TSCH= 11, /** Analysis Return Pointer */ CSL_CHIP_ARP= 12, /** SPLOOP Inner Loop Count Register */ CSL_CHIP_ILC= 13, /** SPLOOP Reload Inner Loop Count Register */ CSL_CHIP_RILC= 14, /** Restricted Entry Point Address Register */ CSL_CHIP_REP= 15, /** E1 Phase Program Counter */ CSL_CHIP_PCE1= 16, /** DSP Core Number Register */ CSL_CHIP_DNUM= 17, /** Saturation Status Register */ CSL_CHIP_SSR= 21, /** GMPY Polynomial.A Side Register */ CSL_CHIP_GPLYA= 22, /** GMPY Polynomial.B Side Register */ CSL_CHIP_GPLYB= 23, /** Galois Field Polynomial Generator Function Register */ CSL_CHIP_GFPGFR= 24, /** Debug interrupt enable register */ CSL_CHIP_DIER=25, /** Task State Register */ CSL_CHIP_TSR= 26, /** Interrupt Task State Register */ CSL_CHIP_ITSR= 27, /** NMI/Exception Task State Register */ CSL_CHIP_NTSR= 28, /** Exception Flag Register */ CSL_CHIP_EFR= 29, /** Exception Clear Register */ CSL_CHIP_ECR= 29, /** Internal Exception Report Register */ CSL_CHIP_IERR= 31 } CSL_ChipReg; /** @} */ /* CHIP global function declarations */ extern Uint32 CSL_chipWriteReg ( CSL_ChipReg reg, CSL_Reg32 val ); extern Uint32 CSL_chipReadReg( CSL_ChipReg reg ); #ifdef __cplusplus } #endif #endif
