Edge-active or static Strobe?
As a standard the Strobe is edge-active, i.e. the input conditions on the Strobe input
are accepted with rising edge and maintained until the next edge. For some applications
it is sensible to use the Strobe in a manner of a gate function. In that case the Strobe
signal is static, i.e. the input signals are accepted for as long as the Strobe signal is
set (or for as long as the gate is open).
