The DINx pins are the frame-sync port digital inputs that receive data from another device for daisy-chain operation. The number of DOUTx pins (or data lanes) is programmed by the DP_TDM[1:0] bits of the DP_CFG1 register. Depending on the level of DP_TDM[1:0] programming, unused DOUTx pins automatically change state to DINx input pins. The exception is the DOUT1 pin which remains as an output. If daisy-chain mode is not used, tie the DINx pins to ground or use pull-down resistors. Do not let the DINx pins float.
