Hi, all. We are designing a carrier board for the CM4. After reading through the documentation, I have become confused about the `GLOBAL_EN` and `RUN_PG` signals. I have gathered the following:
[*] After a software shutdown is complete, GLOBAL_EN should be pulled LOW for >1 ms and then HIGH to boot the CPU back up. Alternatively, the power can be removed and then replaced to boot the CPU.
[*] To do a hard reset of the CPU only, pull RUN_PG LOW and then HIGH again.
[*] To do a hard reset of the power of all components, pull GLOBAL_EN LOW and then HIGH again.
Can anyone here confirm if this is correct?
Thanks!
