Hi ,

In TRM there is a phase like this: 

Also within the BOOTCTRL register, the default boot mode for use with Get boot can be
changed.

what does it mean actually ? 

Best Regards .

    Furkan,

    By default if BOOTMODE pin (GPIO72/GPIO84) value is 1/1 then device selects "Get Mode" and boots devices accordingly. If user wants ROM code to decode value 1/1 as some other BOOTMODE (not "Get Mode", refer "Table 3-7. Get Mode Decoding on CPU1" in TRM for detail about different options) then they can configure the bit 15:8 of BOOTCTRL location and change it. (e.g. if you configure this with value 0x7 then 1/1 will be decoded as "CAN Boot 0". Hope this is clear.

    Please note that you should always use Emulation BOOT method to try this before configuring the BOOTCTRL location in OTP.
