Symbol names ending with underscore N—for example, NAME_N—indicate active LOW signals.
Use a decoupling capacitor of 0.1 F on all V
I = input; O = output; I/O = digital input/output; OD = open-drain output; AI/O = analog input/output;
P = power or ground.
The ISET pin is powered by REG3V3. All other digital pins are powered by V
For the decoupling capacitor requirement, refer to Table 7-7 of Universal Serial Bus Specification Rev. 2.0 .
