SPI Receive Data Register
RD: Receive Data
Data received by the SPI interface is stored in this register right-justified. Unused bits read zero.
PCS: Peripheral Chip Select Status
In master mode only, these bits indicate the value on the NPCS pins at the end of a transfer. Otherwise, these bits read
as zero.
TD: Transmit Data
Data which is to be transmitted by the SPI interface is stored in this register. Information to be transmitted must be writ-
ten to the transmit data register in a right-justified format.
PCS: Peripheral Chip Select
This field is only used if Variable Peripheral Select is active (PS = 1) and if the SPI is in master mode.
If PCSDEC = 0:
If PCSDEC = 1:
