In the example programs I can see that the Fiv value used is derived from
Fdiv = ( pclk / 16 ) / baudrate ;    /*baud rate */

How it has been derived . I cannot see any explanation from the manual. Afterwards this value is used in Setting the DLM and DLL as:
LPC_UART1->DLM = Fdiv / 256;                           
LPC_UART1->DLL = Fdiv % 256;

Can any one please tell how the Fdiv value has been derived.?
