Walking the loop
S, R, CLK are given externally
is the last value of P
compute all other values
anything changed → new event iteration
Reason for unexpected behaviour
t = 10.5.a → "correct" output Q =
= 0
but another iteration of the event loop follows - with T = 0
this changes Q back to 1
is the last value of P =
0
