SLVSD02D March 2015 – June 2019 TPS65982
The two Type-C ports in this design support DisplayPort simultaneously on both ports. When a system is not capable of supporting video on both ports the system controller will disable DisplayPort on the second Type-C port through I2C. Table 16 lists the DisplayPort configurations supported in the system. Table 17 lists the summary of the TPS65982 GPIO signals control for the HD3SS460. Although the HD3SS460 is able to multiplex the required AUX_N/P signals to the SBU_1/2 pins, they are connected through the TPS65982 for additional support of custom alternate mode configurations.
