 W = A * B * C

 Y = F + G
 Z = H * I + J * K



DESCRIPTION:

format of the boolean equations:

  output pin = boolean function of input and output pins

  in this mode is no feedback of output pins allowed, this means that a output
  pin can not be a function of output pins again

 
 *: AND
 +: OR
 /: NEGATION

 Example: Pin Y is HIGH if pin F OR pin G is HIGH, else Y will be LOW.

	  Y = F + G
