#184595 - at89c51RE2 Responding to: ???'s previous message |
let me ask one more question) I checked the formula for internal BRG speed (given in manual for at89c51RE2 on 84p: http://www.atmel.com/dyn/resou...63.pdf)and there are much oа misunderstanding of "X2" bit option. In my application I have T0 & T1 busy in their tasks and UART0 and UART1 require to be running both in master "3" mode, but 0 with 9600 bauds and "1" with 2400 bauds. I understand how to setup values for SCON, BDRCON, BRL and ES, but please explain what should be loaded in BRL and all mess with mentioned "X2" bit (and around) programming. |
