Notes:
1. By connecting I2C to the header's pin 1 and 3, this is
to give I2C access to external I2C master;
2. By installing R926 and R927, FTDI can also access Aux
I2C port (also removing R87 and R88). This feature is not
expected to be used.
3. Normal use: FTDI controls I2C port; Header is connected
to Aux port in SPI configuration.
