XTAL frequency for Serial RS232

According to the 8051 text book, in order to generate a standard baudrate used for serial rs232 coomunication, the XTAL frequency has to be 11.059MHZ. My current project uses a 14.318MHZ XTAL. Is...

I can't select external XTAL (ADuC7026)

Hi, well i am using de ADuC7026 and have problems in configure the external clock. I can't debug if i put at the beginning of main(): // PLLKEY1=0xAA; // PLLCON=0x01; // PLLKEY2=0x55; // dummy1=27;...
