The SMPTE UHD-SDI TX registers are available when Enable AXI4-Lite Interface is selected in the Vivado IDE. The SMPTE UHD-SDI TX IP core register space is shown in Table: SMPTE UHD-SDI TX IP Core Register Space.
IMPORTANT: This memory space must be aligned to an AXI word (32-bit) boundary.
All registers are in little endian format as shown in This Figure.

Notes:
1.Access type and reset value for all the reserved bit in the registers is read-only with value 0.
2.Register accesses should be word aligned and there is no support for a write strobe. WSTRB is not used internally.
3.Only the lower 7 (6:0) of the read and write address of the AXI4-Lite interface are decoded. This means that accessing addresses 0x00 and 0x80 results in reading the same address as 0x00.
4.Reads and writes to addresses outside this table do not return an error.
