The component offers the following features (if they are supported by the hardware) :

• Simple byte access
  The component provides simple methods allowing to read/write individual bytes (SetByte, GetByte etc.)

• Virtual page
  If the Page size property is set to a value greater than zero, a virtual page is created. The virtual page is an array located in RAM and the content of the whole array can be transferred between this virtual page and EEPROM by using the methods SetPage and GetPage. Individual bytes of the virtual page can be accessed by using the methods GetBytePage, SetBytePage etc.

  The address pointer within the virtual page can be automatically pre-incremented if the methods GetActBytePage, SetActBytePage are used. The address pointer is set by methods SetBytePage, GetBytePage. It is set to -1 in the after-reset initialization code.

• Methods can wait for the end of the operation or exit immediatelly
  The write methods can wait until the writing is finished or exit immediatelly. This option can be controlled at runtime by the SetWait method. The Busy method can be used for a detection, whether the EEPROM is ready for the next operation or not.

• Interrupt based implementation
  If the EEPROM device support interrupt and Interrupt service/event property is enabled, the OnWriteEnd and OnWritePageEnd events are available. These events are invoked from all write methods when the write operation finishes.

• Automatic address increment
  The address pointer in the EEPROM can be automatically pre-incremented if the methods GetActByte, SetActByte are used. The address pointer is set by the methods using address as a parameter, such as GetByte, SetByte, GetWord, SetWord, GetLong, SetLong. Methods GetPage, SetPage set this pointer to the last address of the page. In the after-reset initialization code, the address pointer is set to the begin of the selected address range.

  See also automatic address increment for Virtual page described above.

  The address pointer is set also by the methods EraseEeprom and EraseSector to the address passed as a parameter - 1.

• ERR_BUSY - device is busy (command was not completed)
• ERR_RANGE - operation access memory outside valid bounds

The component properties Start address and Used size have to be configured properly for a correct memory mapping. Please note that the component allocates a memory range itself and it mustn't overlap with the EEPROM memory segment defined in the build options tab of the CPU component (because it is not possible to use memory both in the component and in the compiler). So if the component is used, corresponding memory area at build options must be either disabled or adjusted respectively.
