Compute Module • [CM5] Clarifying PMIC_EN vs PWR_BUT Usage for Power Control and Watchdog

2.16. PMIC_EN
Pulling this pin low puts the CM5 in the lowest possible power-down state.
 TIP
It is recommended to only pull this pin low once the OS has shut down.
2.17. PWR_BUT
Pulling this pin low will either power up the CM5 if it has previously been shut down, or power down the CM5 if held low.
This signal is typically connected to a button to function as a power button. If PWR_EN is low for longer than 5 seconds the
CM5 will be forced shutdown.
