Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
SSI Transmit FIFO Raw Interrupt Status
Indicates that the transmit FIFO is half full or less, when set.
SSI Receive FIFO Raw Interrupt Status
Indicates that the receive FIFO is half full or more, when set.
SSI Receive Time-Out Raw Interrupt Status
Indicates that the receive time-out has occurred, when set.
SSI Receive Overrun Raw Interrupt Status
Indicates that the receive FIFO has overflowed, when set.
