NRF52840 pwm needs a pull up?

[Uminn]

I am currently working on getting a pwm to work on port 0 pin 1. I am using the dev board, and a custom board. 

when I use pwm_pin_set_usec(pwm_dev, 1, 5000, 2500); it will only work when I add a pull up on the line.

if i try to use port 0 pin 5 on the dev board it will work fine. but it is defaulted high. is there a way to configure port 0 pin 1 to do pwm without a pull up?

Pin 0 and 1 are by default connected to the 32 kHz crystal on the DK, see the documentation.
