Reverse engineering of the MCU firmware is different from a typical ARM binary. There is no header for IDA to recognize sections and segments, no file system, all the memory space is flat. Hardware specific operation and very low level hardware interoperation makes reversing an MCU firmware more complicated.

Whenever an interrupt occurs, the context switch happens. That means the processor moves from thread mode to the handler mode. As shown in this figure below, …

It detects SWARM external memory accesses and executes them using the AMBA AHB master interface. It monitors the interrupt inputs (nIRQ, nFIQ) and triggers an ISS-internal interrupt using the SWARM API. The wrapping behavior advances the system’s simulated time according to the ARM7 clock definition.
WebSVC and Software Interrupt Instruction (ARM7). If you have used traditional ARM processors (such as the ARM7), you might know that they have a software interrupt instruction (SWI). The SVC has a similar function, and in fact the binary encoding of SVC instructions is the same as SWI in ARM7.
