1.Explain the Mode 1 operation of serial communication. How is configurable baudrate achieved for serial communication in Mode 1? What is the Timer 1 auto reload count for a baudrate of 9600 bits/second for a system working at 11.0592MHz?
2. What is multiprocessor communication? Explain the multiprocessor communication for 8051 for serial communication Mode 2
3. How a ‘power on reset’ can be implemented for an 8051-based system? Explain the changes that happen to various registers and internal RAM on a proper reset.
4. Explain the two power saving modes Idle and Power Down modes for 8051. What is the difference between the two? Explain the methods of terminating each of the power saving modes.
