Hi,
I'm currently trying to understand the OCOTP and Fusemap on the iMXRT1062.
Seems my Teensy4.1 came with the MAC0 (Fusemap 0x620 & 0x630) location
programmed... Is that supposed to be pre-programmed?
According to the 1060's reference manual, that should be all zeros (with each OTP
bit then programmable to 1).
Note, its possible that I am not correctly reading the fusemap (see below).
More (already posted similar question to iMXRT forum)...
I'm having a hard time understanding how to correlate between what appears to be three different
descriptions and mapping of the same things...
If anyone understands this and wants to give me a paragraph of explanation, I'd sure appreciate it.

- the Fusemap Descriptions Table (section 22.3) which uses addresses between 0x400 and 0x8c0
- the Fuse Shadow Memory Footprint (section 23.4.2) which uses addresses from 0x00 thru 0x3f
- the OCOTP register bank
If anyone understands this and wants to give me a paragraph of explanation, I'd sure appreciate it.
