6:5SET_POWER_STATER/U00This field represents the snooped value of the AUX write to DPCD address 0x00600. When AUX_SNOOP_DISABLE = 1’b0, the TUSB546-DCI will enable/disable DP lanes based on the snooped value. When AUX_SNOOP_DISABLE = 1’b1, then DP lane enable/disable are determined by state of DPx_DISABLE registers, where x = 0, 1, 2, or 3. This field is reset to 2’b00 by hardware when CTLSEL1 changes from a 1’b1 to a 1’b0.
4:0LANE_COUNT_SETR/U00000This field represents the snooped value of AUX write to DPCD address 0x00101 register. When AUX_SNOOP_DISABLE = 1’b0, TUSB546-DCI will enable DP lanes specified by the snoop value. Unused DP lanes will be disabled to save power. When AUX_SNOOP_DISABLE = 1’b1, then DP lanes enable/disable are determined by DPx_DISABLE registers, where x = 0, 1, 2, or 3. This field is reset to 0x0 by hardware when CTLSEL1 changes from a 1’b1 to a 1’b0.
