A very special feature of the ARM processor is its conditional execution. By way of example, here is a list of branch instructions understood by the Intel 8086 . Copy a register into the PSR MSR CPSR, R0 ; Copy R0 into CPSR MSR SPSR, 14 Aug 2017 You can use this instruction to write to any CP14 or CP15 coprocessor writable register.
