Enabling the FFB:  P2800 = 1 
Enabling individual FFB including assigning a priority: 
  P2801[3] = 2   OR 1 
  P2801[4] = 2   OR 2 
  P2802[3] = 3   Timer 4 
  P2801[0] = 1   AND 1

  Timer 4, OR 1, OR 2, AND 1 
The function blocks are interconnected using BICO technology (refer to Section 
3.1.2.3). In so doing, the function blocks can be connected with one another as 
well as to other signals and quantities as long as these signals / quantities have the 
appropriate attribute (BO, BI, CO and CI).
