Missing CDOG documentation

[stefano-quantic]

For iMXRT1176, the reference manual (IMXRT1170RM rev. 2, 06/2023) has just a paragraph of explanation about the CDOG (Code Watchdog Timer, formerly abbreviated CWT) peripheral, explaining very little about the peripheral.
There is no documentation at all about the relevant registers.

There is application note AN12912, but it refers to a different MCU family, and some names are different (and the behavior is likely different in some respects too).

Where can I find more information about the CDOG?

Hi @stefano-quantic ,

As CDOG is one of the secure modules in RT117x, you have to refer to the secure reference manual for more details. Please kindly refer to chapter 15 of https://www.nxp.com/webapp/sps/download/mod_download.jsp?colCode=IMXRT1170SRM&appType=moderated for details. 

You may also refer to the demo in the SDK for more details, in which you may find the demo of "SDK_2_14_0_MIMXRT1170-EVK\boards\evkmimxrt1170\driver_examples\cdog" . 

Hope that helps,

Have a great day,
Kan
