**     Filename  : Byte1.C
**     Project   : RTOSDemo
**     Processor : MC9S12DP256BCPV
**     Beantype  : ByteIO
**     Version   : Bean 02.019, Driver 01.03, CPU db: 2.87.283
**     Compiler  : Metrowerks HC12 C Compiler
**     Date/Time : 16/06/2005, 21:10
**     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                   : B
**
**         Initial direction           : Output (direction cannot be changed)
**         Initial output value        : 255 = 0FFH
**         Initial pull option         : off
**
**         8-bit data register         : PORTB     [1]
**         8-bit control register      : DDRB      [3]
