XROW Bytes
Application
in FM0
Several Application Program Interface (API) calls are available for use by an application pro-
gram to permit selective erasing and programming of Flash pages. All calls are made by
functions.
All these APIs are described in detail in the following document on the Atmel web site.
The EXTRA ROW (XROW) includes 128 bytes. Some of these bytes are used for specific pur-
pose in conjonction with the bootloader.

bit ENBOOT in AUXR1 Register
Is Initialized with BLJB Inverted.
Example, if BLJB=0, ENBOOT
is set (=1) during reset, thus the
bootloader is executed after the
reset.
