Application Schematics for HDMI controllers with TOW GPIOs for HDMI Interface Control
Some HDMI driver chips may have two GPIOs to control the HDMI interface chip. In this case a flexible power
saving mode can be implemented. The LS_OE and CT__CP_HPD are active-high enable pins. They control the
TPD12S015A power saving options according to the following table:
