DR14

         The DW_apb_ssi data register is a 16/32-bit (depending on SSI_MAX_XFER_SIZE) read/write buffer for
the transmit/receive FIFOs. If the configuration parameter SSI_MAX_XFER_SIZE is set to 32, then all 32 bits
are valid, otherwise, only 16 bits ([15:0]) of the register are valid. When the register is read, data in the
receive FIFO buffer is accessed. When it is written to, data are moved into the transmit FIFO buffer; a write
can occur only when SSI_EN = 1. FIFOs are reset when SSI_EN = 0.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.
