Flash Memory
6.1.3 Flash memory programming
6.1.4 Boot block swapping
The internal flash memory can be programmed in three different ways:
• Programming via self-programming
• Programming via N-Wire interface
• Programming with external flash programmer
While the self-programming mode can be initiated from the normal operation
mode the external flash programmer mode is entered immediately after
release of a system reset. Refer to “Operation Modes“ on page 114 for details
on how to enter normal operation or external flash programming mode.
The microcontrollers with flash memory support secure boot block swapping.
For comprehensive information concerning secure boot block swapping refer
to the application note “Self-Programming” (document nr. U16929EE), which
explains also the functions of the self-programming library. The latest version
