I changed the IO of the SPI and could not receive the data.

I changed the IO of the SPI and could not receive the data.

Hardware: nrf52832 DK two

Software: nRF5_SDK_17.0.2_d674dde\examples\peripheral\spi
and nRF5_SDK_17.0.2_d674dde\examples\peripheral\spis

Change IO definition
csn_pin = 29;
miso_pin = 12;
mosi_pin = 13;
sck_pin = 30;

It is found that the spi server cannot receive the data, and the spi master can receive the
correct data!

I have tried setting the io output to H1H0 and frequency = 8M but still cannot receive data
normally

I've had some issues with pin 12-13 on the PCA10040 with SPI, those connector pins seems a bit too capacitively loaded. Can you share an analog and/or digital scope of the spi communication?
