How does the processor pipeline handle instruction fetch latency?
In Cortex M0/M3 processors, with a single memory space for both instructions and data accessed via the memory bus, how can the processor handle data reads (e.g., for load/store instructions) if the bus is continually busy fetching instructions? How does the processor pipeline handle instruction fetch latency, and what mechanisms are in place to manage execution if instruction fetches take more than one cycle?

Hey man @Daniel kalu for cloud connectivity with ARM microcontrollers and W5500 controllers, platform SDKs are generally recommended for easier development and better security per say

The Cortex-M0/M3 processors use pipelined instruction fetch, separate fetch and access stages, buffering, prefetching, cache, and out-of-order execution to manage instruction fetch latency and handle data reads while the bus is busy fetching instructions. If instruction fetches take more than one cycle, the processor stalls the pipeline
