PI2DPX2063 Document Number DS43839 Rev 2-2 www.diodes.com BYTE 17 Bit Type Power-up Condition Comment 7 RO 0 Reserved 6 RO 0 5 RO 0 4 RO 1 3 RO 0 2 RO 1 1 RO 0 0 RO 0 BYTE 18 (DPCD Address 00101h: Lane Count Set) Bit Type Power-up Condition Comment 7 RO 0 LANE_COUNT_SET Main-Link Lane Count = Value. Bit<4:0>LANE_COUNT_SET Three values are supported. All other values are RESERVED. Note: Because the upstream device is required to set this value within the MAX_LINK_RATE register (DPCD Address 00001h), there is no power-on reset default value for this field. It is suggested to program this field to 1h. (See the Note within the description for the LINK_BW_SET register (DPCD Address 00100h.) 1h = 1 lane (Lane 0 only) 2h = 2 lanes (Lanes 0 and 1 only) 4h = 4 lanes A Source device may choose any lane count as long as it does not exceed the capability of the DPRX. For DPCD Ver.1.0: Bits <7:5> = RESERVED. Read all 0’s. For DPCD Ver.1.1: Bits <6:5> = RESERVED. Read all 0’s. Bit 7 = ENHANCED_FRAME_EN 0 = Enhanced Framing symbol sequence is not enabled. 1 = Enhanced Framing symbol sequence for BS and SR is enabled. Appli- cable to SST-only mode. A DPTX must set this bit to 1 when the DPRX has the ENHANCED_FRAME_CAP bit in the MAX_LANE_COUNT register (DPCD Address 00002h, bit 7) set to 1. 6 RO 0 5 RO 0 4 RO 0 3 RO 0 2 RO 1 1 RO 0 0 RO 0 BYTE 19 - 30 (Reserved) |
