On the GPIOs of some ARM-based microcontrollers, you are given a register BSRR which you can write to to perform atomic changes in a ports output register. For example, to set Port A Bit 5 to a 1 you simply do GPIOA->BSRR = (1<<5) This alleviates the problem of atomicity so you do not have to perform a read-modify-write sequence.
