The CPU detects an interrupt request with the highest priority.
On detecting an interrupt, the CPU pushes the contents of PC, PSR, r0-r3, r12 and LR to the stack then
An ISR requires specific programming according to the application to be used. This section describes what

An ISR normally pushes register contents to the stack and handles an interrupt as required. The Cortex-

Interrupt requests with higher priority and exceptions such as NMI are accepted even when an ISR

If an interrupt source is set as level-sensitive, an interrupt request continues to exist until it is cleared
If an interrupt is set as edge-sensitive, clear an interrupt request by setting the corresponding value
