  • To my knowledge, there are no magic about that address.

    Most NXP ARM chips just has a specific address where a program can store magic values and if the boot loader internal to the chip sees any of these magic values then it will lock down the chip, i.e. not activate read-out functionality in IAP/ISP and block the JTAG interface.

    An interesting thing is that too large startup code can result in the startup code reaching this magic address - and the startup code just may contain one of the magic values that will activate one of the code read-protect modes.
