spi Miso problem

[Nero]

Hello,

I am using nRF SDK 12.2.0 , with nRF52832 on pca10040 hardware, and working with the example in examples/peripheral/spi/main.c to develop a driver for LIS2DE12. When I write a hexadecimal value I find a problem. I checked with the scope that CS, MOSI and SCK are correct, but I get 0xFF on MISO line .

Any ideas what to check?

the problem is that I can read the default values of the registers, but when I try to write and read the register at the same time but I encounter a problem (a byte of ORC bits which is added during the write) this a example CTRL_REG1(0x20)

Thanks!

@Jørgen I feel like I send ORC byte in writing, because when reading I always read ORC octect in the register
