Write a program in PLP assembly that repeatedly reads the value of the switches $($address: $0$xf$0100000)$ and

displays a pattern on the LED array based on what switches. Each time the switch value is read, the pattern

should be displayed $($regardless of whether the switch value has changed or not since the last time it was read$).$

The table below indicates the pattern that should be displayed for each possible switch setting:

Switch

Hexadecimal

Switch Value

Binary

Switch Value

Decimal

Switch Value

LED Pattern

$00$x$000000010$b$000000011$ Turn on LEDs $0,1,2,$ and $3,$ then set all $8$

LEDs to off

$10$x$000000020$b$000000102$ Turn on LEDs $4,5,6$ and $7,$ then set all $8$

LEDs to off

$20$x$000000040$b$000001004$ Create a scrolling pattern that moves

from right to left starting with LED $1$ and

skipping every other LED. Only one LED

should be on at any given time $($i$.$e$.,$ LED

$1,$ then LED $3,$ then LED $5,$ then LED $7)$

and the pattern should end with all LEDs

off.

Other Other Other Other All LEDs off

Hint: Logical shifts are not required to complete this project, but they can be used to make your program shorter

and more readable than hard coding every value to be written to the LEDs. Shifts can also be useful to generate

the value that you compare with the value of the switches.
