35.8.3 SPI Receive Data Register

Name: SPI_RDR

Address: 0xF0000008 (0), 0xF0004008 (1)

Access: Read-only

• RD: Receive Data

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

Note: When using variable peripheral select mode (PS = 1 in SPI_MR) it is mandatory to also set the WDRBT field to 1 if the

SPI_RDR PCS field is to be processed.
