Part Number: MSP430F5418

1.The customer feedback our LSA1420 table fixed value to appear the confusion phenomenon，Use the simulator to view the fixed value parameters as shown in the figure below:

The starting address of the value parameter :0x025a00

The fixed value parameter is shown below:

2.As described above, the internal Memory storage of MSP430F5418 is abnormal，But some of the Numbers are strange, like "37" and "05".How do these variables come about?

Does the above abnormal situation occur when Memory is frequently erased in a short period of time?MSP430F5418 internal FLASH wipe life is what?

This table has been installed on the site for only more than 2 months now, is it caused by the above problems caused by too many times of wipe or storage exceptions caused by other reasons?

    Hello,

    Thank you for your post. There are several Flash memory related errata for the MSP430F5418. Please read through the erratasheet and implement the workarounds if they haven't been done so already. For example, FLASH30 errata is related to a problem that affects how addresses are decoded for info memory, creating read disturb issues for code executed out of information memory.

    For the workaround, no code should be executed from INFO memory. Also, data stored in INFO memory can only be accessed using code executed from the lower 64K of the memory map. Such accesses to INFO memory are unaffected by the problem.

    Regards,

    James
