For Serial Communication,,i have to set baud rate-9600 in my LPC2148 Microcontroller??
i am using Keil software....How to set that??Reply as soon as possible?

U1DLM:U1DLL = 15.00 MHz / [16 x Baud]
= 15.00 MHz / [16 x 9600]
= 97 =0x0062
U1DLM = 0x00;
U1DLL = 0x62;

i had one doubt??in tat calculation,,U1DLM:U1DLL=15MHZ/(16*Baud)...
Whether the divisor 16 mentioned 16-bit??

Can u say me how to set the PLL??Like what registers are used to set to PLL-12MHZ??

Do you want to change the freq of VPB bus from 15Hz(default) to 12MHz?
