It is desired to design a microcomputer system with interrupted input/output. Draw the block diagram of a system consisting of CPU, RAM memory, 8-bit register and 7-segment display. Addressing mechanism will not be shown. Only data bus connections will be shown. The display unit is driven by the register.

Instruct the system in the main program such that the Interrupt Service Routine is at address 5000 and the stack memory starts at address 8000. Then enable interrupt and wait for the interrupt to come in the main program.

Write a service routine such that when the interrupt arrives the CPU jumps to the Interrupt Service Routine and transmit data stored in the address A000 to the display unit and then returns to the main program.
