I kind of suspect that the 9-bit mode may have started as manual use/abuse of partity. I don't think so, because the 8051 has specific hardware filtering based on the 9th bit. Controlled by SM2 - see: http://www.8052.com/tutser.phtml#Serial Mode you don't need any automatic address management Note that this is in the "bog standard" 8051 UART, where you still had to do the address filtering "manually". The enhanced UART added the automatic address recognition. |
