INSTRUCTION NAME: MIDSEL (middle selector)
DESCRIPTION: This instruction selects the middle value of three inputs. This middle value then
becomes the SVA output. One input is the SVA input, and the other two inputs are analog values
stored in general registers or loadable functions. An additional analog value is stored as a dead
band value, which is used to determine the status of the SVD output. If the difference between the
highest value and the middle value is greater than the dead band value, or if the difference between
the middle value and the lowest value is greater than the dead band value, the SVD output is 1.
Otherwise the SVD output is 0.
