SPIS of nrf52 could not read the data accuracy

I am working with SPIS example ( sdk version 15.3). SPI master send data regulaly. For example, it sent 5ms cs low, but there are only two bytes transferred, the first byte at begin of 5ms, other one at the end. SPIS of nrf52 not read the second one, what can I do with it?

What i ask is, if master send these data to me, i should received two bytes, am i right?
But in fact, only one bytes could be received.

 Ok. So the issue is not that you are missing a lot of information in between the two bytes, but that you only read the second byte. Now I understand. And you only get the second byte, was that so? So you are missing the first?

Can I see how you set up, and how you read your SPI(S) on the nRF? Can you try with the SDK\examples\peripheral\spis example?

I know some mcu could solve the problem, like PIC16f1823

But i believe 52832 is more strong than PIC16f1823. Am i right?
