Introduction
Power-on and reset
The USB controller is disabled and reset after a hardware reset generated by:
But another available and optionnal reset source is :
In this case, the USB controller is reset, but not disabled (so that the device remains attached).
The next diagram explains the USB controller main states on power-on:
Figure 19-7. USB controller states after reset
When the USB controller is in reset state:
• Serial resistors on USB Data lines must have 22 Ohms value (
• Traces from the input USB receptable (or from the cable connection in the case of a tethered
• Voltage transcient / ESD suppressors may also be used to prevent USB pads to be damaged
• U
• A 10µF capacitor is highly recommended on VBUS line
• USBE is not set
