This SMPTE UHD-SDI TX IP supports only HLG HDR.
When AXI4-Lite registers are enabled (C_INCLUDE_AXILITE is true), user needs to program ST352 payload accordingly, through registers allocated. As per ST 2082-10_2018 specification, bits 4 and 5 of byte 2 in the payload are used to configure HLG HDR.
When AXI4-Lite registers are disabled (C_INCLUDE_AXILITE is false), use the Native SDI interface ports for sending ST352 payload information. Refer Table: Native SDI Signals for the ST352 related ports
