In the large memory model, MSP430 instructions have some useful properties when
performing byte, word or address-word writes to registers or memory:
- Byte-writes to registers clear bits 19:8
- Word-writes to registers clear bits 19:16
- PSImode writes to memory clear bits 16:4 of the second memory
