3.8 Bootloader configuration for Atmel RF4CE
The embedded bootloader configuration to support Atmel RF4CE [2] applications is primarily the same as for the
common embedded bootloader, but it also provides additional APIs to support Over-the-Air upgrade and the persistent
data storage feature that can be used by RF4CE applications. The APIs provided by the serial bootloader and the
additional APIs for RF4CE, both make use of self-programming functions. These extra APIs to support Over-the-Air
upgrade and persistent data storage are written into the RWW section (the bootloader section). These APIs can also be
used by other applications for the purposes as listed below:
• Storing the persistent data (for example, NIB) in the flash memory
• Clearing the persistent data (for example, clear NIB)
