The general rule-of-thumb is that the baud rate tolerance allowed is < +/- 4%. Any more than that may accumulate a bit timing error across the byte being decoded at the other end. Therefore, to achieve 460800 bps, the 8x input can be between 3.538944 MHz to 3.833856 MHz. I ...

Other Parts Discussed in Thread: MSP430F5437, MSP430F5438, MSP430G2553 Customer wants to use UART for flash programming using internal oscillator. The internal oscillator has very big tolerance. Wondering what's the max baud rate we can use to ensure the UART communication is robust....
frame-error tolerance From the previous section, we have 8ΔTRX<0.30TTX8ΔTRX<0.30TTX Now our final-bit-sampling margin is a variable; we’ll use M (previously we used 20%). As you can see from the following equation, M must be entered as a decimal, not a percentage. ...
as the possible baud rates are usually a factor of the internal clock speed of the transceiver – in this case the actual baud rate will deviate from the requested baud rate by a certain percentage, but so long as the deviation is within a certain tolerance then communication should still wo...

The UART Emulator baud rate is24000000/(4*N), whereNis an integer between 52 and 65535. RX Baud Rate Tolerance The UART Emulator runs at an interval that is 4 times the baud rate, and goes through these states for each bit: RX start bit detection + TX ...
