Is stop mode suitable for RTC and GPIO working?

in application needs GPIO and RTC working while in power down mode!

then what is the suitable power down mode ?

stop mode? or even RTC mode?

I understand GPIO state can not be changed in stop mode,

so if GPIO state changed is necessary for every fixed time(ex. 1 second)

, then I can wake STM32 up, change the GPIO state ,and back to stop mode again! this can achieve power saving !
