**     Filename  : Bit3.C
**     Project   : dy
**     Processor : MC9S08QD4CSC
**     Beantype  : BitIO
**     Version   : Bean 02.068, Driver 03.13, CPU db: 2.87.049

**     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                    :

**         Port name                   : PTA
**
**         Bit number (in port)        : 2
**         Bit mask of the port        : $0004
**
**         Initial direction           : Output (direction can be changed)
**         Safe mode                   : yes
