**     Filename  : DQ.C
**     Project   : Digital_Thermometer
**     Processor : MC9S08JM60CLHE
**     Beantype  : BitIO
**     Version   : Bean 02.071, Driver 03.16, CPU db: 3.00.033

**     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                   : PTD
**
**         Bit number (in port)        : 0
**         Bit mask of the port        : $0001
**
**         Initial direction           : Output (direction can be changed)
**         Safe mode                   : yes
**         Initial output value        : 0
