IO Expander
The Zynq Ult MPSoC Carrier board supports one “TCA6416A” GPIO 16
-Bit port Expander. This GPIO 16-Bit port
Expander controls the enable pin of USB type-C Switch, SFP+ Control signals and FMC Control Signals. This GPIO 16-Bit
port Expander is connected to PS I2C0 through level translator. The GPIO 16-Bit port Expander I2C address is 0X72.
The pinout details for IO Expander are given as below.
