Description:
If a positive edge is received at input 1 (clock pulse input C, Clock) the signal is transferred 
from signal input 2 (data input D) to the output. 
TRUE at the Master Set input sets the output to TRUE. TRUE at the Master Reset input sets the 
output to FALSE. 
 
Via the output buffer, the output signal is globally available.  
 
Master Set and Master Reset are connected parallel with the function and change the state of 
the function as soon as the signal is present.
