Is it possible switch SPI master role to slave role?

[sugarchai]

Hi, I'm using PCA10001 connect to a sensor chip.I would like to set the register values for sensor chip as SPI master role and I need to switch to slave role to read the sensor data from sensor chip. Unfortunately, I couldn't get any sensor data from sensor chip.I've used an oscilloscope to verify that the data of sensor chip is being sent out from MOSI ,clock and SS PIN.Is it possible to implement the SPI master and slave role together? Thanks.
