OR performs a Boolean OR
XOR performs an exclusive OR
NOT performs a Boolean negation of its input
QOR qualified OR
S force a Boolean output to TRUE
R force a Boolean output to FALSE

Below are the available blocks for managing Boolean signals:

RS reset dominant bistable
SR set dominant bistable
R_TRIG rising pulse detection
F_TRIG falling pulse detection
SEMA semaphore
FLIPFLOP flipflop^bistable
