How to double the baud rate in 8051? - Ques10
Web23 Mar 2016 · 8051 has a serial port to transfer and receive data serially. The 8051 transfers and receives data serially at many different baud rates. The baud rate in the 8051 is programmable. This is done with the help of Timer 1. In the case of XTAL = 11.0592 MHz, the machine cycle frequency is 11.0592 MHz / 12 = 921.6 kHz 921.6 kHz .
