Hi,
I have not so familiar with the SCON setting hope someone can help me.
I already refer the datasheet of 80c51 instruction set (pg. 11).
- The SM0 and SM1 is SET mean Serial Port mode is 9-bit UART.
- SM2 and REN, i have not so understand what the datasheet have mean!!?
- The table 6. MODE-3 show SCON=F0H and SM2 Variation = Multiprocessor Environment (SM2=1). What does it mean?
When we have to use 9-bit UART? and when we have to use this MODE-3?
Please advice...
Thank you.
