CCS/MSP430F1611: System Reset and Initialization

Antoine Tantin

Part Number: MSP430F1611

Tool/software: Code Composer Studio

Hello,

I am currently using the MSP430F1611 in order to run it in Low Power Mode 3 (LPM3). My program is finished and works well when I am not in LPM3. So I implemented the LPM3.

And that is the point where I have some issues. It works, but I have no more Power-On Reset (POR) neither RST/NMI reset.

I have tried to discover what is the problem, and when i just put the MSP in LPM3, the reset works, but when I add the "__bic_SR_register_on_exit(LPM3_bits) " instruction in order to leave the LPM3 in an interrupt, it leaves and the program works but I can not reset any more my microcontroller.

Could explain me the issue ?

Thank you,

Antoine

How exactly are you trying to trigger the POR or RST? What happens then?

What does your main loop do after it has been woken up?

Hello,

thank you for the answer. I think I finally found my issue. I wrote some data in the flash memory and I should have disturbed something. I change the storage address of my data and it works well.

Thanks,

Antoine
