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]).
