hal_nvic_status_t hal_nvic_restore_interrupt_mask(uint32_t mask)
This function restores the IRQ settings as specified in the mask.
hal_nvic_status_t hal_nvic_register_isr_handler(hal_nvic_irq_t irq_number, hal_nvic_isr_t isr_handler)
This function is used to register a callback (an ISR) for NVIC IRQ.
