PRODUCTION DATA
The TPS25763-Q1 supports the DisplayPort alternate mode as a DP sink. To enable HPD signaling through PD messaging, a single pin is used as the HPD input and output. When events occur on these pins during a DisplayPort connection though the Type-C connector, hardware timers trigger and interrupt the digital core to indicate needed PD messaging. When a port is operating as a DP source, its corresponding HPD pin operates as an output (HPD TX). The TPS25763-Q1 port operates as a DP sink, and the corresponding HPD pin operates as an input (GPIO0 set to HPD RX). When DisplayPort is disabled in the application configuration, HPD is disabled and the GPIO operates as generic input/output pin.
For additional information regarding GPIO and I2C support when interfacing to a DP Alt Mode sink-side cross point switch, refer to Section 8.3.12.1 and Section 8.3.13, respectively.
