Write a program in Cthat reads a 3-bit desired light patternfromthe 3 input switches connected to pinsP2.3-P2.5and displays the patternon the 8 LEDs (pins P1.0-P1.7) with some light playing options based on the input from other 3 switches(pins P2.0-P2.2).

[8] 4.a)Switch on Port2.0 (Read/Rotatemode)?On(logic 0)Readmode: Your program continuously reads the switches and takes only the 3-bits (Port 2.3-2.5) as a desired display pattern and displaysthem on the LEDs (Port 1.3-1.5). All other LEDs on Port 1 are masked to zero (turned off). ?Off(logic 1) Rotate mode: Once this switch is turned off, your program will rotate the pattern on the 8 LEDs connected to Port1 pins 0-7. The pattern is the 3-bit value you constantly updated and saved during the Read mode.

[6] 4.b)Switch on Port2.1 (Left/Right direction mode) ?On (logic 0) The LED pattern rotates to the Left.?Off (logic 1) The LED pattern rotates to the Right.

[6] 4.c)Switch on Port2.2 (Fast/Slow speed mode) **Hint: Software Delay**?On (logic 0) The patternrotation is Fast.?Off (logic 1) The patternrotation is Slow.

[2] 4.d

Modify the program

so that the two Switches on Port2.0-1 provide four different

fun patterns which continuously display/move on the 8 LEDs. Keep Switch on Post 2.2 to

change speed

//you need to modify the toggle line below with pattern

rotation based on the value of P2.1

R6_LED ^= 0xFF;

//toggle pattern

//mask any excessive bits

//you need to replace the simple delay line below with

slow/fast delay based on P2.2
