**     Filename  : IRQ.C
**     Project   : taxi_meter
**     Processor : MC9S08JM60CLHE
**     Component : ExtInt
**     Version   : Component 02.094, Driver 01.19, CPU db: 3.00.046
**     Compiler  : CodeWarrior HCS08 C Compiler
**     Date/Time : 2010-1-5, 21:23
**     Abstract  :
**         This bean "ExtInt" implements an external 
**         interrupt, its control methods and interrupt/event 
**         handling procedure.
**         The bean uses one pin which generates interrupt on 
**         selected edge.
**     Settings  :
**         Interrupt name              : Vkeyboard
**         User handling procedure     : IRQ_OnInterrupt
**
**         Used pin                    :
**             ----------------------------------------------------
**                Number (on package)  |    Name

**             ----------------------------------------------------
**
**         Port name                   : PTG
**
**         Bit number (in port)        : 0
**         Bit mask of the port        : $0001
