QSPI usage of pins based on sdk_config

[Christoph2020]

Platform: nRF52840 { development kit }
SDK: nRF5_SDK_16.0.0

Can sdk_config be used to remap any pins for used a SCK and MOSI and MISO?
Specifically, can the following mapping work: #define SPI_MOSI_PIN 21, #define SPI_SCK_PIN 19

Is the output voltage on the pins 3.3v or 5v?

Hi

Yes, there should be no problems with using these P0.21 and P0.19 for MOSI and SCK pins respectively in a QSPI application. As for the GPIO levels, when in normal voltage mode, the GPIOs will output equal to the voltage supplied to the VDD pin, while in VDDH mode, it will equal to the level specified in the REGOUT0 register. See the Infocenter for more information.

Best regards,
