/** ###################################################################
** THIS BEAN MODULE IS GENERATED BY THE TOOL. DO NOT MODIFY IT.
** Filename : Byte1.C
** Project : RTOSDemo
** Processor : MC9S12C32CFU
** Beantype : ByteIO
** Version : Bean 02.019, Driver 01.03, CPU db: 2.87.276
** Compiler : Metrowerks HC12 C Compiler
** Date/Time : 10/05/2005, 11:49
** 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 : 0 = 000H
** Initial pull option : off
**
** 8-bit data register : PORTB [1]
** 8-bit control register : DDRB [3]
