PMC MIO[46:47] I2C0 Bus
[Figure 3, callout 11]
Bus I2C0 connects the XCVC1902 U1 PS bank 501 and the XCZU4EG system controller U125
PS bank 501 to a GPIO 16-bit port expander (TCA6416A U233) and I2C switch (TCA9548A
U33). The port expander enables accepng various fan controller, FMCP connector, and power
system status inputs. Bus I2C0 also provides access to power system PMBus power controllers
and INA226 power monitors, as well as three SI570 components via the U33 TCA9548A switch.
TCA6416A U233 is pin-strapped to respond to I2C address 0x20. The TCA9548A U33 switch is
set to 0x74.
