The Uart baud rate generation formula is,
UARTn baudrate = PCLK/16*UnDL
UnDL = 256 × UnDLM + UnDLL
why the Divisor latch MSB is multiplied with 256
plz inform me,
thank you
...than what you can retrieve yourself.
In fact, people on this forum don't even have access to that - because you didn't bother to mention what specific chip you are talking about!!
