Smod in 8051

WebIf SMOD = 1, the baud rate is 1/32 the oscillator frequency. In the 80C51, the baud rates in Modes 1 and 3 are determined by the Timer 1 overflow rate. In case of Timer2, these baud … Web22 Aug 2013 · The 8051 microcontroller serial communication UART circuitry divides the machine cycle frequency of 921.6 kHz by 32, before it is used by Timer 1 to set the baud rate. Therefore, 921.6 kHz divided by 32 gives out 28,800 Hz. 4. When Timer 1 is used to set the baud rate it must be programmed in mode 2, that is 8-bit auto reload.
