[
, callout
The VC707 board implements a single I
2
C port on the FPGA (IIC_SDA_MAIN,
IIC_SDA_SCL), which is routed through a 1-to-8 channel I
2
C bus switch (U52). The bus
switch can operate at speeds up to 400 kHz.
The bus switch I
2
C address is
0x74
(
0b01110100
) and must be addressed and configured
to select the desired downstream device.
