It's plainly memory-mapped, as the vast majority of other resources in these chips, due to the huge address space... So either you learn how to map variables (linker script stuff), or you resort to the low-level *(type_you_want *)(address_you_want).

Cast a pointer to the structure at the address of the OTP, and access the structure via that point. Some basic C
