**     Filename  : Bit1.C
**     Project   : vvvf_56F8346
**     Processor : 56F8346
**     Beantype  : BitIO

**     Abstract  :
**         This bean "BitIO" implements an one-bit input/output.
**         It uses one bit/pin of a port.
**         Methods of this bean are mostly implemented as a macros 
**         (if supported by target language and compiler).
**     Settings  :
**         Used pin                    :
