I have questions about Flash memory in MSP430F249.
1.Is there a possibility that data in flash memory will be destroyed by repeated power ON/OFF cycles?
2. What is the type of flash memory in MSP430F249, "NAND type" or "NAND type"?
3.In the 3.2 Flash Endurance chapter of the URL, there is a statement that Flash endurance is 10000 cycles.
Do you have information on the cause and probability of occurrence when data is destroyed by reading or writing flash memory?
4.When writing data to Flash memory, is it necessary to take measures against bad blocks (bad sectors) in Flash memory?
[Background of the question]
The phenomenon of data corruption occurred when MSP430's Flash memory was repeatedly powered on and off.
Flash memory control register (FCTL2) is set to 400 kHz.
It is set to information memory segment B (start address 0x1080), and word write was performed.
Of the total size of segment B of 64 bytes, 38 bytes are used.
