Hi psp1004umd,
this MCU has the following "informational" Flash Memory:
Size 256 Byte in 4 Segments á 64 Bytes, Flash 010FFh to 01000h
There is a library colled "MspFlash.h" which you can include in your script. With this, you can use the segments B, C and D. A is protected so far.
You should be aware of the contraints when writing Flashmemory, you always have to erase the hole segment first:
Example:
#define Flash1 SEGMENT_B // Alarmdata (AnzAlarme * 3 bytes, max. 21 Alarme moeglich/possible)
#define Flash2 SEGMENT_C // Configdata ( 1 byte "Bundesland" (region))
