**     Filename  : KBI1.C
**     Project   : key_scan
**     Processor : MC9S08JM60CLHE
**     Beantype  : Init_KBI
**     Version   : Bean 01.022, Driver 01.09, CPU db: 3.00.033

**     Abstract  :
**          This file implements the KBI (KBI) module initialization
**          according to the Peripheral Initialization Bean settings, and defines
**          interrupt service routines prototypes.
**          The KBI module is the serial peripheral interface module,which allows 
**          full-duplex, synchronous, serial communications with peripheral devices.
**          The keyboard interrupt module (KBI) provides a few independently maskable 
**          external interrupts. When a port pin is enabled for keyboard interrupt 
**          function, an internal pullup/pulldown device is also enabled on the pin.

**     Settings  :
**          Bean name                                      : KBI1
