DLPC410: Unused Pins

Part Number: DLPC410
Other Parts Discussed in Thread: DLP7000

I am designing a control board--upon which the DLCP410 resides--to control a DLP7000. Therefore, data buses D and C are not required. Do I need to connect the DIN, DVALID or any other pins related to these buses to ground or should they be left floating?

Hello again KB,

On our EVM they are left unconnected when used with a DLP7000 since there are pads for two flex cables but the second is not used.

During initialization the controller requests the DMD ID and determines if the C & D bus should be initialized, both inbound and outbound. Do not connect them to ground.
