The HDMI TX and RX I/O signals are assigned to VE2802 XPIO Bank 702. Some of these signals such as I2C buses, HDMI_TX_SRC, and HDMI_RX_SNK have voltage translation to 5V connected to the HDMI receptacle. The block diagram in the following figure shows the I/O signal connections for HDMI TX and RX. A 128-Kbit EEPROM is provided for storing HDMI EDID metadata in the circuitry.
