**     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]
