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

**             ----------------------------------------------------
**
**         Port name                   : PTD
**
**         Bit number (in port)        : 3
**         Bit mask of the port        : $0008
**
**         Initial direction           : Input (direction cannot be changed)

**     Method      :  Key3_GetVal (component BitIO)
**
**     Description :
**         This method returns an input value.
**           a) direction = Input  : reads the input value from the
**                                   pin and returns it
**           b) direction = Output : returns the last written value
**         Note: This bean is set to work in Input direction only.
