Is SPI certain pins not working in SDK_11.0.0 ?

Hi,

I did try to SPI Example with SPIFlash(winbond 25x20cl) in SDK 11.0.0.

My testing condition is that

  • nRF5_SDK_11.0.0

  • nRF52-DK, (V 0.9.0)

  • SPI example

So, I want to check to certain Pin for SPI.

Basically, I did successfully check to SPI Communication.

Which pin configuration is that

  • SPI0_CONFIG_SCK_PIN 25

  • SPI0_CONFIG_MOSI_PIN 24

  • SPI0_CONFIG_MISO_PIN 23

  • SPI_CS_PIN 22

However, when I only changed pin configuration to others that

  • SPI0_CONFIG_SCK_PIN 18

  • SPI0_CONFIG_MOSI_PIN 17

  • SPI0_CONFIG_MISO_PIN 16

  • SPI_CS_PIN 15

, I checked wrong response data on SPI.

Did not that pins(18/17/16/15) use SPI ? or Is any configure to something ?

Thanks.
