P0.06 is always high level on the PCA10040 board

[tianbing357]

Hi, p0.06 is always high lever when the following codes are executed:

nrf_gpio_cfg_output(6);
nrf_gpio_pin_clear(6);

Why?

Softdevice is used in the project.

Can it be that you have uart enabled (or log with uart enabled), since P0.06 is used by UART TXD by default (see back of the board).

You are correct, thank you very much.
