Tiny microcontrollers use these handlers to wake up from "sleep mode" to save battery life, only processing data when a specific interrupt is triggered. Best Practices for Implementation

void ivthandleinterrupt(void) uint32_t current_mask = __get_BASEPRI(); uint32_t incoming_irq = get_current_irq_number(); if (get_priority(incoming_irq) < current_mask) // Allow nesting – re-enable high-priority interrupts __set_BASEPRI(get_priority(incoming_irq)); ivthandleinterrupt

Handling software exceptions ( int 80h in Linux). The Lifecycle of an Interrupt Hardware Signal: A device raises an interrupt line. Tiny microcontrollers use these handlers to wake up
