Most (if not all?) of the SAM3X8E's memory-mapped registers are 32-bit. However, memory accesses of size 8 and 16 bits are also supported by the CPU. I am wondering if there are any issues associated with accessing, particularly writing, registers with memory operations of a smaller size? For examp…
