Write a RISC$-$V OTTER interrupt$-$driven assembly language program that does the following. Each time the program receives an interrupt, the program averages the $32$ unsigned bytes starting at address $0$xFF$00$ in memory, and outputs that average to address given below. After an interrupt, remain in the background task until the program detects the button associated with the right$-$most bit value on the input is pressed. Assume that some external device has the ability to write data to the RISC$-$V memory.

Minimize the number of instructions in your program

Don$$t do I$/$O from the foreground task

BUTTONS: PORT$\_$ADDRESS $=0$x$11008004$

Output port: PORT ADDRESS $=0$x$11001100$
