Bits 19:16 – PCS[3:0] Peripheral Chip Select
In Host mode only, these bits indicate the value on the NPCS pins at the end of a transfer. Otherwise, these bits are read as zero.
Note: When using Variable Peripheral Select mode (FLEX_SPI_MR.PS = 1), it is mandatory
to set the FLEX_SPI_MR.WDRBT bit to 1 if the PCS field must be processed in
FLEX_SPI_RDR.
Bits 15:0 – RD[15:0] Receive Data
Data received by the SPI Interface is stored in this register in a right-justified format. Unused bits are read as zero.
