Hi,

Would you describe the relationship(logic) between "User configuration DCSM OTP bank0(0x78000-0x783FF)+User configuration DCSM OTP bank1(0x78800-0x78BFF)"  and

"DCSM Zone1 + DCSM Zone2 "?

Thanks~

Best regards~

Xin

    Hi Chen,

    For this device, USER configuration DCSM OTP bank1 is not applicable. Where do you see the description for the same?

    Also dual zone model (DCSM Zone1 and DCSM Zone2) is for third party development. Basically two different developer can have their own secure zones with out sharing the code but can still call each other functions. If that's not needed then user can use just one zone.

    Hi Vivek,
    That is to say "User configurable DCSM OTP Bank 1 (0x0007 8800-0x0007 8BFF)" can be used as common OTP for stroring data?But "User configurable DCSM OTP Bank 0(0x0007 8000-0x0007 83FF) " is used for configuration of DCSM Zone1 and DCSM Zone2.
    Thanks~&Best regards~

    Hi Xin,

    No, USER OTP can not be used as common OTP for storing data.
