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.
When using Variable Peripheral Select mode (PS = 1 in SPI_MR), it is mandatory to set SPI_MR.WDRBT bit if the PCS field must be processed in 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.
