35.8.3 SPI Receive Data Register

Name: SPI_RDR

Address: 0x40088008

Access: Read-only

 RD: Receive Data

Data received by the SPI Interface is stored in this register in a right-justified format. Unused bits are read as zero.

 PCS: Peripheral Chip Select

In Master 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 (PS = 1 in SPI_MR), it is mandatory to set the WDRBT field to 1 if the PCS field must

be processed in SPI_RDR .
