Register access protection

Hello,

Regarding access protection registers (PCNS, PCNP, ICNS, and ICNP) for the MCX A microcontroller, they are mentioned in the user manual, but not described.

Would it be available a description for these registers?

Thanks!

OK. Thanks!

Re: Register access protection

Hello JosG,

Update:

As TrustZone is not present on this device, these registers are not used. We will request to correct RM

Thanks,

Jun Zhang
