Two IR sensors (i.e., IR1 and IR2) at two different doors in a room are connected to the MCU 8051 through pin P3.1 and P3.6, respectively. A common anode seven-segment display unit, given in Fig.1 as follows, is connected with MCU 8051 through Port 2 only. Assume an external oscillator of 36 MHz in connected with MCU 8051. Write the ASM code in MCU 8051 for the following working mechanism of the system: Once any of the sensors (i.e., IR1 or IR2) senses any external movement of an incoming visitor through the doors (i.e., sends logic high values to the corresponding slots of Port 3), blink F (i.e., the room is Full) in the display unit for 2400 times with a duty cycle of 60%, otherwise show E (i.e., the room is Empty) in

the display unit if none of the sensors senses anything (i.e., no movement). Show your calculation in detail considering both the ON-state and OFF-state delay for the given duty cycle. Consider the total period is 30 ms.
