8.4 USB to I
Figure 8.4 Application Example showing USB to I
This example shows the CNFGx pins set for mode 011 – I
Only two signal lines are required for I
data line is bi-directional.
Examples of I2C peripherals include EEPROMs, Real time Clocks (RTC) and audio or video codecs.
The unused pins may be left unterminated.
Power to the USB port is enabled by the VBUSCTRL# signal
