Hi.
Give me answer, please.
I have serial programming adapter PRGS430 and microcontroller MSP430F1121I. I can download my program into microcontroller, erase, verify or read out.
But, microcontroller reset unstable.
i.e when i press down button RESET (in programmer) or set to 0 and then 1 pin RST/NMI or when i turn off and then turn on power, my program is run or not is run. I collected scheme in compliance with guideline in datasheet MSP-PRGS430.
What is wrong?

MSP430F1121 RESET

Hi brother! The solution for Your problem is very simple! The MSP430F1121 do not have internal voltage supervisor and problem may occurs in case do you not connect.
Search in www.ti.com more details about voltage supervisor and selected the device for Your convenience. Its all!
