Functioning the nRM1300 SHPHLD without a battery

[vadima]

The nRM1300 PS states that "The SHPHLD pin has an internal pull-up resistor RSHPHLD to VBAT.".

1. Does the SHPHLD operate as a reset control when a battery is disconnected (when charging is complete) or a battery isn't available?
2. Does the SHPHLD is pulled to another internal power source when the VBAT isn't supplied?
3. May the SHPHLD pin be pulled to some other external power source?

Thank you for  your feedback.But I asked about the RESET function of the SHPHLD pin, not the shipping hold function.

The nPM1300 PS states in Section  "7.5 RESET — Reset control" the following:
The SHPHLD pin is a reset control, in addition to being used for exiting Ship and Hibernate mode.

"A long logic-low (> tRESETBUT ) on SHPHLD causes a power cycle and resets the whole system. This feature is
enabled by default after power-up,"

The SHPHLD pin is active Low, When the battery is disconnected (or not available) the RSHPHLD is pulled nowhere. Which level has the SHPHLD pin in this situation and how the reset function is executed?

If you remove the battery, the ship hold function is disabled. When you connect the battery again, you have to enable ship hold it this is needed.

Once more. I'm not interesting in the ship hold function.
I want to know how the RESET function is executed when the internal pull-up RSHPHLD is float (the VBAT pin isn't externally connected).

It's not designed to be operated without a battery.
