LPC4330 UARTbaudrate

Page 1134 of the User Manual gives the equation for the UARTbaudrate. Section 40.6.3 on page 1123 of the User Manual states that :”… the baud rate clock, which must be 16x the desired baud rate”. Does this mean that the UARTbaudrate equation on page 1134 must generate a baud rate that is 16x the desired baud rate?



The following UARTbaudrate equation is copied from page 1134 of the User Manual:

 UARTbaudrate = PCLK / (16*(256*DLM+DLL)*(1+DivAddVal/MulVal)).


Is the above equation correct or should the equation be (note added parentheses around (DLM + DLL)):

 UARTbaudrate = PCLK / (16*(256*(DLM+DLL))*(1+DivAddVal/MulVal))?
