Description

FIFO data read with no FIFO pop.

Fields

RXDATA

Received data from the FIFO.

RXSSEL0_N

Slave Select for receive. This field allows the state of the SSEL0 pin to be saved along with received data. The value will reflect the SSEL0 pin for both master and slave operation. A zero indicates that a slave select is active. The actual polarity of each slave select pin is configured by the related SPOL bit in CFG.

RXSSEL1_N

Slave Select for receive. This field allows the state of the SSEL1 pin to be saved along with received data. The value will reflect the SSEL1 pin for both master and slave operation. A zero indicates that a slave select is active. The actual polarity of each slave select pin is configured by the related SPOL bit in CFG.

RXSSEL2_N

Slave Select for receive. This field allows the state of the SSEL2 pin to be saved along with received data. The value will reflect the SSEL2 pin for both master and slave operation. A zero indicates that a slave select is active. The actual polarity of each slave select pin is configured by the related SPOL bit in CFG.

RXSSEL3_N

Slave Select for receive. This field allows the state of the SSEL3 pin to be saved along with received data. The value will reflect the SSEL3 pin for both master and slave operation. A zero indicates that a slave select is active. The actual polarity of each slave select pin is configured by the related SPOL bit in CFG.

SOT

Start of Transfer flag. This flag will be 1 if this is the first data after the SSELs went from deasserted to asserted (i.e., any previous transfer has ended). This information can be used to identify the first piece of data in cases where the transfer length is greater than 16 bit.
