**     Project   : NODE_A
**     Processor : MC9S12C64CFA16
**     Beantype  : TimerOut
**     Version   : Bean 02.146, Driver 01.10, CPU db: 2.87.339

**     Abstract  :
**         This bean implements a periodic signal generator 1:1 (Flip-Flop Output).
**         The signal alternates the "0" and "1" output values in exactly
**         regular intervals; that is why the time length of the "0" part
**         of one pulse is equal to the "1" part of one pulse.
