MSP430F5310: MSP430F5310

Hi Nidheesh,

After a full reset or your power up ramp, the PMU will allow execution to begin. There is some low-level boot code that executes, and then the device checks for BSL signature and BSL protect value, (Shown in flowchart below - See section 1.2 of Creating a Custom Flash-Based Bootloader for more details on device BSL Startup Sequence). This tells the device whether or not to boot up in BSL mode. After those checks the device will normally run the C_INIT code, and then jump to the user application code (assuming BSL was not invoked). 

Best Regards,
Brandon Fisher
