I'm trying to run TLC 5946, but my controller lacks signals.

I'm trying to run the LED using your TLC 5946. In my controller, SIN, SCLK, XLAT, and BLANK signals come out. However, the GS CLK and Mode signals required by TLC 5946 do not come out. GS CLK, is there any way to drive TLC 5946 without a mode signal? If not, can you create GS CLK, Mode using SIN, SCLK, XLAT, and BLANK? I'll wait for a quick reply.
