Rotate instruction does not function as expected
When repeated rotate instructions (rrcm, rram, rrum and rlam) are applied on the Program Counter(PC), unexpected instruction execution may occur.
Insert a NOP instruction between sequential rotate instructions performed on the PC register.
Refer to the table below for compiler-specific fix implementation information.
