How to Use This Document
(1) Purpose and Target Readers
This manual is designed to provide the user with an understanding of the functions and characteristics of the
Self-Programming Library. It is intended for users designing application systems incorporating the library. A
basic knowledge of embedded systems is necessary in order to use this manual. The manual comprises an
overview of the library, API description, usage notes and cautions.
Particular attention should be paid to the precautionary notes when using the manual. These notes occur within
the body of the text, at the end of each section, and in the Cautions section.
The revision history summarizes the locations of revisions and additions. It does not list all revisions. Refer to

Full form
A piece of software located in the Boot Cluster handling
the reprogramming of the device
Embedded Flash where the application code or
constant data is stored.
Embedded Flash where mainly the data of the
EEPROM emulation are stored.
Dual operation is the capability to access flash memory
during reprogramming of another flash memory range.
Dual operation is available between Code Flash and
Data Flash.
Between different Code Flash macros dual operation
depends on the device implementation.
Error Correction Code
EEPROM Emulation Library
Electrically erasable programmable read-only memory
In distinction to a real EEPROM the EEPROM
emulation uses some portion of the flash memory to
emulate the EEPROM behavior. To gain a similar
behavior some side parameters have to be taken in
account.
Code Flash Library (Code Flash access layer)
Data Flash Library (Data Flash access layer)
Software protection of flash memory against
programming and erasure. Not present in all devices.
Firmware is a piece of software that is located in a
hidden area of the device, handling the interfacing to
the flash.
Electrically erasable and programmable non-volatile
memory. The difference to ROM is, that this type of
memory can be re-programmed several times.
A flash block is the smallest erasable unit of the flash
memory.
