nRF52832 P0.20 high on powerup

[Emil]

Hello,

We're developing a project on a custom board based on nRF52832 and noticed that P0.20 is high on powerup, even with no firmware.
Is there a way to controll the pin on powerup so it's low?

You need external pull down here. All pins are disconnected, i.e floating before they are defined. If you measure a high level, something else is pulling this high
