IMXRT1060 and OCOTP shadow registers

[g_volokh]

Hi All.

I am working with IMXRT1060 and see that it has OTP Fuses in the address range 0x400..0x8CF.

The OCOTP works with OTP Fuses via shadow registers. Shadow registers have the address range 0x0000..0x003F.

Question:

- how does one relate to other?

- OCOTP can read, reload and write to/from shadow registers, but how can I write to OTP Fuses?

Thanks and regards,

George Volokh.

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) How does one relate to others?
-- The relation between the Fuse and shadow register like the below show.

fuse_address = fuse_index * 0x10 + 0x400
2) OCOTP can read, reload and write to/from shadow registers, but how can I write to OTP Fuses?
-- Please learn it by referring to 23.4.1.2 Fuse and Shadow Register Read and 23.4.1.3 Fuse and Shadow Register Writes sections in the RM.

Have a great day,
TIC
