#104456 - Enhanced UART - SADDR, SADEN Responding to: ???'s previous message |
The Standard 8051 UART supports the 9-bit "multiprocessor" mode, but the Enhanced UART does the automatic address recognition.
Automatic address recognition is controlled by two Special Function Registers: SADDR and SADEN. So, if your variant doesn't have these, I guess it doesn't do automatic address recognition! See http://www.intel.com/design/mc...266801.pdf and http://www.intel.com/design/mc...049001.pdf |
