Processor Expert generates definitions of all hardware register structures to the file IO_Map.h. The Processor Expert type definitions are generated to the file PE_Types.h which also containins definitions of macros used for a peripheral register access.

Types

Type	Description	Supported for
byte	8-bit unsigned integer (unsigned char)	all
bool	Boolean value (unsigned char) (TRUE = any non-zero value / FALSE = 0)	all
word	16-bit unsigned integer (unsigned int)	all
dword	32-bit unsigned integer (unsigned long)	all
dlong	array of two 32-bit unsigned integers (unsigned long)	all
TPE_ErrCode	Error code (uint8_t)	all except MPC55xx

Structure for images

typedef struct {          /* Image */
  word width;             /* Image width in pixels */
  word height;            /* Image height in pixels */
  byte *pixmap;           /* Image pixel bitmap */
  word size;              /* Image size in bytes */
  char *name;             /* Image name */
} TIMAGE;
typedef TIMAGE* PIMAGE ; /* Pointer to image */

Structure for 16-bit register:

/* 16-bit register (big endian format) */
  typedef union {
     word w;
     struct {
       byte high,low;
     } b;
  } TWREG;
  

Macros

  __DI()             - Disable global interrupts
  __EI()             - Enable global interrupts
  

  EnterCritical()    - It saves CCR register and disable
                       global interrupts
  ExitCritical()     - It restores CCR register saved
                       in EnterCritical()
  

For the list of macros available for Peripheral registers access, please see the chapter Registers Access of the Processor Expert main help.

Constants

Methods Error Codes

The error codes are defined in the PE_Error module. Error code value is 8-bit unsigned byte. Range 0 - 127 is reserved for PE, and 128 - 255 for user.

ERR_OK	0	OK
ERR_SPEED	1	This device does not work in the active speed mode
ERR_RANGE	2	Parameter out of range
ERR_VALUE	3	Parameter of incorrect value
ERR_OVERFLOW	4	Timer overflow
ERR_MATH	5	Overflow during evaluation
ERR_ENABLED	6	Device is enabled
ERR_DISABLED	7	Device is disabled
ERR_BUSY	8	Device is busy
ERR_NOTAVAIL	9	Requested value not available
ERR_RXEMPTY	10	No data in receiver
ERR_TXFULL	11	Transmitter is full
ERR_BUSOFF	12	Bus not available
ERR_OVERRUN	13	Overrun is present
ERR_FRAMING	14	Framing error is detected
ERR_PARITY	15	Parity error is detected
ERR_NOISE	16	Noise error is detected
ERR_IDLE	17	Idle error is detected
ERR_FAULT	18	Fault error is detected
ERR_BREAK	19	Break char is received during communication
ERR_CRC	20	CRC error is detected
ERR_ARBITR	21	A node loses arbitration. This error occurs if two nodes start transmission at the same time
ERR_PROTECT	22	Protection error is detected.
ERR_UNDERFLOW	23	Underflow error is detected.
ERR_UNDERRUN	24	Underrun error is detected.
ERR_COMMON	25	General unspecified error of a device. The user can get a specific error code using the method GetError.
ERR_LINSYNC	26	LIN synchronization error is detected
ERR_FAILED	27	Requested functionality or process failed.
ERR_QFULL	28	Queue is full.
