I have a question regarding the W7500P IAP functionality. In the IAP example for the W7500 there is some functionality for erasing, reading and writing the flash, but I can’t find anything to protect the flash from reading and writing.
The reference manual chapter 9.3.1 states one can read protect the flash by writing the CRL bit in the FLOCKR0 register. But I can’t find which bit the CRL bit is?
According to [url]W7500 flash memory interface registers] it is even not possible to control the flash without the IAP…
So my question is, how can i protect flash from reading and writing?
