**     Filename  : KEY.H
**     Project   : Smoke_Detector
**     Processor : MC9S08JM60CLHE
**     Component : KBI
**     Version   : Component 01.095, Driver 01.20, CPU db: 3.00.046
**     Compiler  : CodeWarrior HCS08 C Compiler
**     Date/Time : 2010-1-25, 17:30
**     Abstract  :
**         This bean "KBI" implements the Freescale Keyboard 
**         Interrupt Module (KBI/KBD) which allows to catch events 
**         on choiced external pins. These pins share one KBI/KBD 
**         interrupt which can be caused by an events on the pins.
**     Settings  :
**         Keyboard                    : KBI 
**         Used pins           
**         Pin 0                       : PTG0_KBIP0
**         Pull resistor               : up
**         Generate interrupt on       : falling
**         Interrupt service           : Enabled
**         Interrupt                   : Vkeyboard
**         Interrupt Priority          : 
**         Enable in init. code        : Yes
**         Events enabled in init.     : Yes
**     Contents  :
**         GetVal  - byte KEY_GetVal(void);
**         SetEdge - byte KEY_SetEdge(byte edge);
