UART BAUD RATE GENERATION

Chaitanya R over 11 years ago

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

What is the reason for multiplying the UnDLM with 256?

At higher baud rates the MSB register will taken the value 0,than why did the 256 is multiplied with msb?

Didn't you realize how obvious the answer is? You know about binary numbers?
