3 ** Filename : Byte1.C

4 ** Project : RTOSDemo

5 ** Processor : MC9S12C32CFU

6 ** Beantype : ByteIO

7 ** Version : Bean 02.019, Driver 01.03, CPU db: 2.87.276

8 ** Compiler : Metrowerks HC12 C Compiler

9 ** Date/Time : 10/05/2005, 11:49

10 ** Abstract :

11 ** This bean "ByteIO" implements an one-byte input/output.

12 ** It uses one 8-bit port.

13 ** Note: This bean is set to work in Output direction only.

14 ** Methods of this bean are mostly implemented as a macros

15 ** (if supported by target langauage and compiler).

16 ** Settings :

17 ** Port name : B

18 **

19 ** Initial direction : Output (direction cannot be changed)

20 ** Initial output value : 0 = 000H

21 ** Initial pull option : off

22 **

23 ** 8-bit data register : PORTB [1]

24 ** 8-bit control register : DDRB [3]
