**     Filename  : Byte1.C
**     Project   : RTOSDemo
**     Processor : MC9S08GT60CFB
**     Beantype  : ByteIO
**     Version   : Bean 02.053, Driver 03.08, CPU db: 2.87.086
**     Compiler  : Metrowerks HCS08 C Compiler
**     Date/Time : 3/7/2006, 6:48 AM
**     Abstract  :
**         This bean "ByteIO" implements an one-byte input/output.
**         It uses one 8-bit port.
**         Note: This bean is set to work in Output direction only.
**         Methods of this bean are mostly implemented as a macros 
**         (if supported by target langauage and compiler).
**     Settings  :
**         Port name                   : PTB
**
**         Initial direction           : Output (direction cannot be changed)
**         Initial output value        : 0 = 000H
**         Initial pull option         : off
**
**         8-bit data register         : PTBD      [0004]
**         8-bit control register      : PTBDD     [0007]
