Registers

Captures the EPIN[n].PTR and EPIN[n].MAXCNT registers values, and enables endpoint IN n to respond to traffic from host

Captures the ISOIN.PTR and ISOIN.MAXCNT registers values, and enables sending data on ISO endpoint

Captures the EPOUT[n].PTR and EPOUT[n].MAXCNT registers values, and enables endpoint n to respond to traffic from host

Captures the ISOOUT.PTR and ISOOUT.MAXCNT registers values, and enables receiving of data on ISO endpoint

Allows OUT data stage on control endpoint 0

Allows status stage on control endpoint 0

Stalls data and status stage on control endpoint 0

Forces D+ and D- lines into the state defined in the DPDMVALUE register

Stops forcing D+ and D- lines into any state (USB engine takes control)

Signals that a USB reset condition has been detected on USB lines

Confirms that the EPIN[n].PTR and EPIN[n].MAXCNT, or EPOUT[n].PTR and EPOUT[n].MAXCNT registers have been captured on all endpoints reported in the EPSTATUS register

The whole EPIN[n] buffer has been consumed. The buffer can be accessed safely by software.

An acknowledged data transfer has taken place on the control endpoint

The whole ISOIN buffer has been consumed. The buffer can be accessed safely by software.

The whole EPOUT[n] buffer has been consumed. The buffer can be accessed safely by software.

The whole ISOOUT buffer has been consumed. The buffer can be accessed safely by software.

Signals that a SOF (start of frame) condition has been detected on USB lines

An event or an error not covered by specific events has occurred. Check EVENTCAUSE register to find the cause.

A valid SETUP token has been received (and acknowledged) on the control endpoint

A data transfer has occurred on a data endpoint, indicated by the EPDATASTATUS register

Details on what caused the USBEVENT event

IN endpoint halted status. Can be used as is as response to a GetStatus() request to endpoint.

OUT endpoint halted status. Can be used as is as response to a GetStatus() request to endpoint.

Provides information on which endpoint's EasyDMA registers have been captured

Provides information on which endpoint(s) an acknowledged data transfer has occurred (EPDATA event)

Control of the USB pull-up

State D+ and D- lines will be forced into by the DPDMDRIVE task. The DPDMNODRIVE task reverts the control of the lines to MAC IP (no forcing).

Controls the split of ISO buffers

Returns the current value of the start of frame counter

Controls USBD peripheral Low-power mode during USB suspend

Controls the response of the ISO IN endpoint to an IN token when no data is ready to be sent
