(a) Write the steps to enable serial interrupts in 8051 (b) If the clock frequency is 11.0592MHz and the variable baud rate is set to 4800 , Find the value for timer TH register in 8051MC. Write an assembly language program to send a string "Invalid input" to a PC through serial communication of the 8051 microcontroller. Use 4800bps,8 data bits, one start bit, one stop bit and no parity bits for the communication. (Assume that the PC will receive data without any crror.)
