void libarm_isr_enable_irq | ( | void |  | ) |
| Re-enable ARM's global interrupts from within an IRQ interrupt service routine. ARM IRQ interrupts are automatically disabled on entry to an interrupt handler and subsequently re-enabled on exit. You can use libarm_isr_enable_irq to re-enable interrupts from within an interrupt handler so that higher priority interrupts may interrupt the current interrupt handler. This call must be accompanied with a call to libarm_isr_disable_irq prior to completion of the interrupt service routine. Note that this call should only be made from within an IRQ interrupt handler.
