52810 P0.16 out-of-control

nrf_gpio_cfg_output(16);
nrf_gpio_pin_set(16);

Set P0.16 to high level under the main part of this routine, test P0.16, and find that the level is not high.

I see that there is a documentation error in the nRF52810 product specification under the pin assignment for the QFN32 package. P0.16 is connected to pin number 13, not pin number 16, which is shown in the picture. Pin number 16 is the P0.21/nRESET pin.

Could this be the reason for the non-functioning GPIO?

If not, please post the schematics and PCB layout of your board for review.
