Where can I find documentation for CoreDebug_DEMCR_TRCENA_Msk

[Claude]

I am using the STM32U575xx and found stackoverflow questions regarding the DWT->CYCLCNT.

c - STM32 - How to enable DWT Cycle counter - Stack Overflow

I tested this and it works fine, but I'd like to have documentation aside from the header file.

I'd like to learn more about

1. CoreDebug->DEMCR bits

2. ITM->LAR

ARM Technical Reference Manuals for the processor core

To a lesser extent ST's Programming Manuals

When I visit this:the PDF gives me no hit for LAR.

However DEMCR is documented. Thanks

For future reference, documentation for LAR (Lock Access Register) can be found here:
