**     Filename  : IEE1.H
**     Project   : ESV1_0_DJ64
**     Processor : MC9S12DJ64BCFU
**     Beantype  : IntEEPROM
**     Version   : Bean 02.056, Driver 01.06, CPU db: 2.87.238
**     Compiler  : Metrowerks HC12 C Compiler
**     Date/Time : 2006-6-10, 10:56
**     Abstract  :
**         This device "IntEEPROM" implements internal EEPROM
**     Comment   :
**         The EEPROM array is organized as rows of word (2 bytes), the EEPROM block's
**         erase sector size is 2 rows (2 words). Therefore it is preferable
**         to use word aligned data for writting - methods SetWord and SetLong -
**         with word aligned address.
**         Driver expects that all security options of EEPROM are disabled.
**         If some security option is enabled methods performing write
**         operation (such as SetWord) can return error.
**     Settings  :
**         EEPROM size                 : 1024 byte
**         Initialization:
**              Wait in methods        : Disabled
**              EEPROM clock           : 181 kHz
**
**     Contents  :
**         SetByte - byte IEE1_SetByte(word Addr,byte Data);
**         GetByte - byte IEE1_GetByte(word Addr,byte *Data);
**         SetWord - byte IEE1_SetWord(word Addr,word Data);
**         GetWord - byte IEE1_GetWord(word Addr,word *Data);
**         SetWait - void IEE1_SetWait(bool Wait);
**         Busy    - bool IEE1_Busy(void);
