Hi
I'm using two different designs using nRF51822 as SPI Slave. One is using p0.07 as CLK input and the other is using p0.06 as CLK input. I'm using the code from spi_slave.c/h without any changes.
The one using p0.07 works like a charm.
Using p0.06 adds a 90Mhz oscillating signal to the clock-pulses and consequently the SPI Slave doesn't understand it.
Are there any default-settings on p0.06 I have to shut off? I'm not using any analog stuff whatsoever.
