What is the lowest power mode for STM32L053C6 that keeps the status of the GP outputs?

[RCapr.1]

Sorry for the dumb question, but I am rather new to this family of products.

I need to have two different possibility to exit a LP mode in different phases: in one case I can wake-up via the internal comparator, and this can be done even in STOP mode, no problem, but in another case I have to be awakened by an external device that is enabled setting one GP output high, so in this case I need to keep the status of that GP output even in the LP mode.

Can I do this in STOP mode, or what is the best alternative LP mode?

Thanks.

Hello,

Yes you can keep the state of the GPIO that you need, and put the rest in analog state in order to save power consumption.
