The behavioral of serial ports on the UV2 Keil Compiler for 8051 is very strange: When I using the Target 1 (Infineon 80517A), the baud don't correspond to specify by software, transmiting at very high more velocity (at same at instructions processing). When using the target standard, the serial dont sent anything (for the same code preview) Is it a failure of Compiler/simulator? What can be it? Thank you.
