#180809 - do not know, but Responding to: ???'s previous message |
Did the 8051 "invent" the 9-bit, "Multiprocessor", UART mode[1] - or was it just implementing an already-established "standard" ?
Do not know, but in the days the '51 were designed the name of the game was Intel. I tend to recall that Motorola et al did not have any microcontroller/microprocessor offerings at the time the '51 was introduced. Now that begs the question: did a mainframe or a minicomputer have this feature? I do not know, but through, I guess, 10 different minicomputers I did not see this feature. never worked mainframes, someone else chime in. anyhow, the idea of networking was not prevalent in (was it) 1985.
