Typedefs
Master Variable Types
These are a set of typedefs to make the size of all variable declarations explicitly known.
typedef unsigned char	boolean
	A typedef to make the size of the variable explicitly known.
typedef unsigned char	int8u
typedef signed char	int8s
typedef unsigned short	int16u
typedef signed short	int16s
typedef unsigned int	int32u
typedef signed int	int32s
typedef unsigned int	PointerType
Functions
External Declarations
These are routines that are defined in certain header files that we don't want to include, e.g. stdlib.h
int	abs (int I)
	Returns the absolute value of I (also called the magnitude of I).
Miscellaneous Macros
#define	BIGENDIAN_CPU   FALSE
	A convenient method for code to know what endiannes processor it is running on.
#define	NO_STRIPPING
	A friendlier name for the compiler's intrinsic for not stripping.
#define	__no_init
#define	EEPROM   errorerror
	A friendlier name for the compiler's intrinsic for eeprom reference.
#define	__SOURCEFILE__   __FILE__
	The __SOURCEFILE__ macro is used by asserts to list the filename if it isn't otherwise defined, set it to the compiler intrinsic which specifies the whole filename and path of the sourcefile.
#define	assert(condition)   do { if (! (condition)) {while (1); }} while(0)
#define	__delay_cycles(x)   please_use_halCommonDelayMicroseconds_instead_of_delay_cycles
	__delay_cycles() is an intrinsic IAR call; however, we have explicity disallowed it since it is too specific to the system clock.
#define	DEBUG_LEVEL   BASIC_DEBUG
	Set debug level based on whether or DEBUG is defined.
#define	APPLICATION_IMAGE_START   ((u32) &__ApplicationFlashStart)
	Set the application start and end address.
#define	APPLICATION_IMAGE_END   ((u32) &__ApplicationFlashEnd)
#define	halResetWatchdog()   halInternalResetWatchDog()
#define	UNUSED
	Define __attribute__ to nothing since it isn't handled by IAR.
#define	SIGNED_ENUM
	Some platforms need to cast enum values that have the high bit set.
#define	STACK_FILL_VALUE   0xCDCDCDCD
	Define the magic value that is interpreted by IAR C-SPY's Stack View.
#define	RAMFUNC   __ramfunc
	Define a generic RAM function identifier to a compiler specific one.
#define	NO_OPERATION()   __no_operation()
	Define a generic no operation identifier to a compiler specific one.
#define	SET_REG_FIELD(reg, field, value)
	A convenience macro that makes it easy to change the field of a register to any value.
#define	simulatedTimePasses()
	Stub for code not running in simulation.
#define	simulatedTimePassesMs(x)
	Stub for code not running in simulation.
#define	simulatedSerialTimePasses()
	Stub for code not running in simulation.
#define	_HAL_USE_COMMON_DIVMOD_
	Use the Divide and Modulus Operations from platform-common.h.
#define	VAR_AT_SEGMENT(__variableDeclaration, __segmentName)   __variableDeclaration __attribute__ ((section (__segmentName)))
	Provide a portable way to specify the segment where a variable lives.
#define	ALIGN_VAR(__variableDeclaration, alignment)   __variableDeclaration __attribute__ ((aligned(alignment)))
char	__ApplicationFlashStart
char	__ApplicationFlashEnd
void	halInternalResetWatchDog (void)
	Macro to reset the watchdog timer.
Global Interrupt Manipulation Macros
Note: The special purpose BASEPRI register is used to enable and disable interrupts while permitting faults.When BASEPRI is set to 1 no interrupts can trigger. The configurable faults (usage, memory management, and bus faults) can trigger if enabled as well as the always-enabled exceptions (reset, NMI and hard fault). When BASEPRI is set to 0, it is disabled, so any interrupt can triggger if its priority is higher than the current priority.
#define	ATOMIC_LITE(blah)   ATOMIC(blah)
#define	DECLARE_INTERRUPT_STATE_LITE   DECLARE_INTERRUPT_STATE
#define	DISABLE_INTERRUPTS_LITE()   DISABLE_INTERRUPTS()
#define	RESTORE_INTERRUPTS_LITE()   RESTORE_INTERRUPTS()
#define	DECLARE_INTERRUPT_STATE   int8u _emIsrState
	This macro should be called in the local variable declarations section of any function which calls DISABLE_INTERRUPTS() or RESTORE_INTERRUPTS().
#define	DISABLE_INTERRUPTS()
	Disable interrupts, saving the previous state so it can be later restored with RESTORE_INTERRUPTS().
#define	RESTORE_INTERRUPTS()
	Restore the global interrupt state previously saved by DISABLE_INTERRUPTS()
#define	INTERRUPTS_ON()
	Enable global interrupts without regard to the current or previous state.
#define	INTERRUPTS_OFF()
	Disable global interrupts without regard to the current or previous state.
#define	INTERRUPTS_ARE_OFF()   ( _basePriIsDisabled() )
#define	INTERRUPTS_WERE_ON()   (_emIsrState == 0)
#define	ATOMIC(blah)
	A block of code may be made atomic by wrapping it with this macro.
#define	HANDLE_PENDING_INTERRUPTS()
	Allows any pending interrupts to be executed.
#define	SET_BASE_PRIORITY_LEVEL(basepri)
	Sets the base priority mask (BASEPRI) to the value passed, bit shifted up by PRIGROUP_POSITION+1.
int8u	_readBasePri (void)
void	_writeBasePri (int8u priority)
void	_enableBasePri (void)
int8u	_disableBasePri (void)
boolean	_basePriIsDisabled (void)
void	_setPriMask (void)
void	_clearPriMask (void)
