**     Project   : touchpanal
**     Processor : MC9S08QG8CDT
**     Beantype  : Init_SPI

**     Abstract  :
**          This file implements the SPI (SPI) module initialization
**          according to the Peripheral Initialization Bean settings, and defines
**          interrupt service routines prototypes.
**          The SPI module is the serial peripheral interface module,which allows 
**          full-duplex, synchronous, serial communications with peripheral devices.

  //       correct functionality of the hardware.
  //
  // Receive interrupt flag is cleared by reading the SPI status register
  // followed by reading the SPI data register.
  // Transmit interrupt flag is cleared by reading the SPI status register
  // followed by write the SPI data register.
  // Mode Fault interrupt flag is cleared by reading the SPI status register
  // followed by write to the SPI control register.
  // Example: Status = SPIS;
  //          DataIn = SPID;
