Hi! I am trying to implement connection with smart card via UART on LPC11uxx. After a few calculation and with help of examples, I understood, that I shlould fill the right values of DLL and DLM to get a nessesary initial frequency (3.57MHz). But, when I configurate DLM = 13 and DLM = 1 using formula Fdiv = SYSCLK/(F*baudrate)  (where F = 372 and baudrate = 9600), a see just a 14,5 KHz. Why? Where  I made mistake?
