Must have depended on variant, the one we used in college would throw a GP fault for misaligned access. It literally didn't have an A0 line. That said it's been over 10 years and I could be remembering the very hard instruction alignment rules as applying to data too...
- monocasa 4y ago16bits had to be aligned. It didn't have an A0 because of the 16bit pathway, but it did have byte select lines (#UDS, #LDS) for when you'd move.b d0,ADDR so that devices external to the CPU could see an 8-bit data access if that's what you were doing.
