checksum in code for CORTEX-M3

Does the user code contains checksum in internal flash without intervention of user?

I read the below statement in LPC-1769 user manual:

When there is no valid user code (determined by the checksum word) in the user flash or
the ISP enable pin (P2.10) is pulled low on startup, the ISP mode will be entered and the
boot code will setup the PLL with the IRC.

 

Best Regards,

Avinash.
