Voltage Ranges for Low & High

[beg_dk]

Hi

When for instance enabling deepsleep and having it wake up when eg. GPIO13 is set to LOW or HIGH like this:

esp_deep_sleep_enable_ext0_wakeup(GPIO_NUM_13, 1);

... what voltage ranges define LOW & HIGH?

Thanks

Data sheet says 30% and 70% of supply voltage

Ok, I found this datasheet:
