The 65XX series was designed, in many ways, to better the 68XX series. 6821 ->6522, 6850 -> 6551. My theory is, at the time, MOS wanted to show Motorola that the little "rag tag" group could take any 68XX design, improve it, cost reduce it, and deliver a better, cheaper option. Adding this capability to the 6551 seems in line with that theory. They didn't have to have a specific use case for it, just enough to suggest it could be useful. JimReceived on 2018-09-05 20:01:26
