Register Name:
Access Type:
Reset Value:
• SOFE: Start of Frame Generation Enable
Set this bit to generate SOF on the USB bus in full speed mode and keep alive in low speed mode.
Clear this bit to disable the SOF generation and to leave the USB bus in idle state.
This bit is set by hardware when a USB reset is requested or an upstream resume interrupt is detected (UHINT.TXRSMI).
• RESET: Send USB Reset
Set this bit to generate a USB Reset on the USB bus.
Cleared by hardware when the USB Reset has been sent.
It may be useful to clear this bit by software when a device disconnection is detected (UHINT.DDISCI is set) whereas a
USB Reset is being sent.
• RESUME: Send USB Resume
Set this bit to generate a USB Resume on the USB bus.
Cleared by hardware when the USB Resume has been sent or when a USB reset is requested. Clearing by software has
no effect. This bit should be set only when the start of frame generation is enable. (SOFE bit set).
