 * sections (although it is necessary for interrupts to be globally disabled
 * extremely briefly as the interrupt mask is updated in the GIC).

 * FreeRTOS functions that can be called from an interrupt are those that end in
 * "FromISR".  FreeRTOS maintains a separate interrupt safe API to enable
 * interrupt entry to be shorter, faster, simpler and smaller.
