Reset priority
“Reset priority” means that if both input signals are active, it
will be the RESET command that is obeyed, causing the
output signal to become inactive (=0). See Table 33.
Set priority
For “Set priority” the determining input signal is SET.
Should both input signals be active, this is resulting in an
activated (=1) output signal. See Table 34.
Edge controlled without priority
The third setting is “Edge controlled”, for which no input
signal has priority over the other. The output signal follows
any of the two input signals (still providing they are at a
positive edge). The most recent registered activity decides the
output. See Table 35.
Should both inputs become activated simultaneously, there
will not be any change; the output signal will just keep its
earlier status.

considered simultaneous if the difference is less than 8
ms.
