Data Transmit Register
The Data Transmit Registers hold the data to be transmitted in the next
transfer. Valid bits depend on the transmit bit length field in the CNTRL register.
For example, if TX_BIT_LEN is set to 0x08 and the TX_NUM is set to 0x0, the
bit TX0[7:0] will be transmitted in next transfer. If TX_BIT_LEN is set to 0x00
and TX_NUM is set to 0x1, the core will perform two 32-bit transmit/receive
successive using the same setting (the order is TX0[31:0], TX1[31:0]).
