During this pandemic situation, the residential apartment fixed a LCD screen that is placed in the main gate to caution the visitor. Assume that a digital infrared (IR) sensor is fixed at the main gate of the apartment for monitoring the visitor. The IR sensor module is connected to the INTO pin of 8051. Whenever a visitor enters in to the apartment, an intemuption will be observed by the IR sensor, then the LCD should display "ENTRY RESTRICTED". Write an 8051 ASM program for the above system. Assume the crystal frequency is 12 MHz.
