The methods for programming the flash memory are shown below.
The code flash memory can be rewritten to through serial programming using a flash memory programmer or external
device (UART communication) or through self-programming.
 Serial programming using flash memory programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash memory programmer. For
details, see 30.4 Serial Programming Method.
 Serial programming using external device (UART communication)
Data can be written to the flash memory on-board through UART communication with an external device (a
microcontroller or ASIC). For details, see 30.2 Serial Programming Using External Device (that Incorporates
UART).
 Self-programming
The user application can execute self-programming of the code flash memory by using the flash self-programming
library. For details, see 30.6 Self-Programming.
The data flash memory can be rewritten to by using the data flash library during user program execution (background
operation). For details about accessing or writing to the data flash memory, see 30.8 Data Flash.
