105 * generic interrupt controller [GIC] means a priority that has a numerical

111 * value below configMAX_API_CALL_INTERRUPT_PRIORITY) cannot call any FreeRTOS
112 * API functions, will nest, and will not be masked by FreeRTOS critical
113 * sections (although it is necessary for interrupts to be globally disabled
114 * extremely briefly as the interrupt mask is updated in the GIC).
116 * FreeRTOS functions that can be called from an interrupt are those that end in
117 * "FromISR". FreeRTOS maintains a separate interrupt safe API to enable
118 * interrupt entry to be shorter, faster, simpler and smaller.
