Description:
This function acts as a classic J-K Latch. When both inputs are less than 1 its re-
sult remains unchanged. When both inputs are greater or equal to 1 its result
toggles between 0.0 and 1.0. If the only input S
n-1
is greater or equal to 1.0 its re-
sult is 1.0, and if the only input A is greater or equal to 1 its result is 0.0.
