PUSH/POP to the Stack Pointer

Register operation (PUSH and POP), when an exception occurs
Arm® Cortex®-M3 automatically performs PUSH and POP functions at the start and end of exception/interrupt handlers.
There are eight registers that automatically performs PUSH and POP; R00R3, R12, R14, R15, and xPSR.
Let's see PUSH and POP operations in a program flow example, when an exception/interrupt event occurs.
