13.10 COMMUNICATION INTERFACE CHARACTERISTICS
13.10.1 USB - Universal Bus Interface
(Operating conditions T
Note 1: RL is the load connected on the USB drivers.
Note 2: All the voltages are measured from the local ground potential.
Note 3: To improve EMC performance (noise immunity), it is recommended to connect a 100nF capacitor
to the USBVCC pin.
