SLVSD02E March 2015 – August 2021 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 10-6 lists the DisplayPort configurations supported in the system. Table 10-7 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.
