32 * Application specific definitions.

44 * The FreeRTOS Quark port implements a full interrupt nesting model.
46 * Interrupts that are assigned a priority at or below
47 * configMAX_API_CALL_INTERRUPT_PRIORITY can call interrupt safe API functions
50 * Interrupts that are assigned a priority above
51 * configMAX_API_CALL_INTERRUPT_PRIORITY cannot call any FreeRTOS API functions,
52 * will nest, and will not be masked by FreeRTOS critical sections (although all
53 * interrupts are briefly masked by the hardware itself on interrupt entry).
55 * FreeRTOS functions that can be called from an interrupt are those that end in
56 * "FromISR". FreeRTOS maintains a separate interrupt safe API to enable
57 * interrupt entry to be shorter, faster, simpler and smaller.
59 * User definable interrupt priorities range from 2 (the lowest) to 15 (the
62 #define configMAX_API_CALL_INTERRUPT_PRIORITY 10
65 * Interrupt entry code will switch the stack in use to a dedicated system
68 * configISR_STACK_SIZE defines the number of 32-bit values that can be stored
69 * on the system stack, and must be large enough to hold a potentially nested
70 * interrupt stack frame.
72 * Changing this parameter necessitates a complete rebuild so the assembly files
75 #define configISR_STACK_SIZE 350
78 * If configSUPPORT_FPU is set to 1 then tasks can optionally have a floating
79 * point context (the floating point registers will be saved as part of the task
80 * context). If configSUPPORT_FPU is set to 1 then a task must *not* use any
81 * floating point instructions until after it has called vPortTaskUsesFPU().
83 * If configSUPPORT_FPU is set to 0 then floating point instructions must never

88 /* There are two ways of implementing interrupt handlers:
90 * 1) As standard C functions -
92 * This method can only be used if configUSE_COMMON_INTERRUPT_ENTRY_POINT
93 * is set to 1. The C function is installed using
94 * xPortRegisterCInterruptHandler().
96 * This is the simplest of the two methods but incurs a slightly longer
97 * interrupt entry time.
99 * 2) By using an assembly stub that wraps the handler in the FreeRTOS
100 * portFREERTOS_INTERRUPT_ENTRY and portFREERTOS_INTERRUPT_EXIT macros. The handler is installed
101 * using xPortInstallInterruptHandler().
103 * This method can always be used. It is slightly more complex than
104 * method 1 but benefits from a faster interrupt entry time.
106 * Changing this parameter necessitates a complete clean build.
