During the transition of privilege levels while performing syscalls, the ARM documentation recommends flushing the pipeline to avoid pre-fetched instructions from being executed with the previous privilege level. The manual says: 4.16 CONTROL register (...) after programming the CONTROL register, an ISB instruction should be used. (...) This is not implemented in the Cortex M0 processor.
