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 . WebDescription: DA adjusts the contents of the Accumulator to correspond to a BCD (Binary Coded Decimal) number after two BCD numbers have been added by the ADD or ADDC instruction. If the carry bit is set or if the value of bits 0-3 exceed 9, 0x06 is added to the accumulator. If the carry bit was set when the instruction began, or if 0x06 was added to …
