Dear TI experts，
I am using MSP4305342 and have some strange problems.
I have 50pcs boards，there are two boards run into the unexpected funtion which locates at code segement 0x22400.
This function is doing some "flash erase" and "flash write".
I can ensure that this function has only one entrance，before this function entering，address 0x22C00 will have some label like "0xA5A5" .
Finally，This funtion entered without the label "0xA5A5"，so I can ensure that this function is entered by accident.
According to the slaz278ab，errata CPU40 is the only CPU errata will happen on MSP430F5342 with IAR FOR MSP430 V6.40.
So I wonder that if my code touches errata CPU40.
My questions are:
1.What wiil cause errata CPU40？I cannot understand clearly through slaz278ab ：(
2.How can I solve errata CPU40？According to the slaz278ab，add some command line would sove.However，when I add these command line，there is nothing changed with my ".bin".
