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). 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.

Provide a portable way to specify the segment where a variable lives.ĪLIGN_VAR(_variableDeclaration, alignment) VAR_AT_SEGMENT(_variableDeclaration, _segmentName) _variableDeclaration _segmentName Use the Divide and Modulus Operations from platform-common.h. Some platforms need to cast enum values that have the high bit set.ĭefine the magic value that is interpreted by IAR C-SPY's Stack View.ĭefine a generic RAM function identifier to a compiler specific one.ĭefine a generic no operation identifier to a compiler specific one.Ī convenience macro that makes it easy to change the field of a register to any value.

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.

These are a set of typedefs to make the size of all variable declarations explicitly known.Ī typedef to make the size of the variable explicitly known.Ī convenient method for code to know what endiannes processor it is running on.Ī friendlier name for the compiler's intrinsic for not stripping.Ī friendlier name for the compiler's intrinsic for eeprom reference. Include platform-common.h last to pick up defaults and common definitions. Use the C Standard Library Memory Utilities from platform-common.h. Use the Master Program Memory Declarations from platform-common.h. Compiler and Platform specific definitions and typedefs for the IAR ARM C compiler.
