Note:

NC = Not Connected

Note: 1 The USB+ pin needs a 1.5kâ¦ pull-up resistor.

2 For 5V applications, VDD must be connected to a 5.0V source. For 3.3V applications, VDD

must be connected to a 3.3V source.

3 These signals can be used on one of two different ports (Port 1 or Port 4) for flexibility.

Default is Port1.
