Your code needs to follow all these requirements or constraints:

$1.$ Your code needs to compute the mean value of the samples in mean.

$2.$ Your code needs to compute the average absolute deviation of the samples in aad.

$3.$ Your code is not allowed to modify the RAM or FRAM otherwise. That means

$-$ Your code is not allowed to modify the samples, buff, or foot.

$-$ Your code is not allowed to create new variables, arrays etc. in RAM or FRAM $($nor

does it need to$).$

$4.$ Your code needs to use indexed mode with the label samples when accessing the

elements in the given array and use the constant LENGTH instead of hardcoded values.

$($This is a good restriction since using indexed mode will actually make your life easier.$)$

$5.$ Your code is allowed to use core registers as needed.

$6.$ Your code must not be wasteful with resources.

$-$ Your code must not use more core registers than necessary.

$-$ Your code must not use unnecessary jumps $($aka no spaghetti$).$

$-$ Your code must not have unnecessary instructions and the like.

$7.$ You code should have comments and use descriptive labels
