nRF52832 and nRF52840 GPIO questions

1.Cant make P0.09(NFC1) and P0.10(NFC2) outputs?

Tried both nRF52832 from PCA10040 and a BT module  with nRF52840 and on both cant make any of those pins outputs. Tried with code and from debugger at a stop point to config as output and set OUT high. Don’t see any error, but don’t have any output voltage. Tried other pins and everything works fine either way – from code or manually form debugger. (On PCA100400 tried and outputs on NFC antenna pins as I saw the Arduino headers are not connected)

Is there any specific settings to make  P9, P10 outputs or any limitations that I missed?

2.Is there way with SES in debug mode to see change on an input pin at debug point? The only way I found is to make a step, but is there a way to stay at the debug point, let say press a button and somehow to refresh the window that shows P0 or P1 IN registers?

Thanks
