GPIOs configurations in low-power Standby Mode: STM32G0B1RET

[Kmax18]

I am using this MCU on a battery-supplied custom board: STM32G0B1RET.
I am looking for clarification re. the GPIO availability in Standby Mode.
Table 26 in Reference Manual RM0444 (see below) seems to offer one of two (exclusive) possibilities:

1. Without wakeup capability: wakeup pins are not available, but I/Os can be configured with internal pull-up, pull-down or floating. That would mean a GPIO pin can be assign 0 in Standby Mode.
2. With wakeup capability: wakeup pins are available, but GPIOs cannot be configured and are floating.

Please confirm. Thank you!

Try RM0444 chapter 7.3.15, but yes isnt very clean.

@TDK, just for clarification re. the STM32G0B1RET on a battery-supplied custom board:  the datasheet states that the pull-down resistor is weak, Table 55 lists around 40kOhm (see below). Can that cause a problem in Standby mode?
Also, one member states that in Standby Mode only RTC pins can drive low.

Please advise, I look forward to resolving this.

I don't see why that would cause a problem.

Not sure, no board here for me to test. Seems like it should work.
