This bit is set when the STALLRQS bit is written to one. This will request to send a STALL handshake to the host.
This bit is cleared when a new SETUP packet is received or when the STALLRQC bit is written to zero.
This bit is set when the RSTDTS bit is written to one. This will clear the data toggle sequence, i.e., set to Data0 the data toggle
This bit is cleared instantaneously.
The user does not have to wait for this bit to be cleared.
This bit is set when the EPDISHDMAS is written to one. This will pause the on-going DMA channel n transfer on any Endpoint n
The user then has to acknowledge or to disable the interrupt source (e.g. RXOUTI) or to clear the EPDISHDMA bit (by writing a
In ping-pong mode, if the interrupt is associated to a new system-bank packet (e.g. Bank1) and the current DMA transfer is
If the interrupt is not associated to a new system-bank packet (NAKINI, NAKOUTI, etc.), then the request cancellation may
This may be used for example to identify erroneous packets, to prevent them from being transferred into a buffer, to complete a
For control endpoints:
The FIFOCON and RWALL bits are irrelevant. The software shall therefore never use them on these endpoints. When read,
For IN endpoints:
This bit is set when the current bank is free, at the same time as TXINI.
This bit is cleared (by writing a one to the FIFOCONC bit) to send the FIFO data and to switch to the next bank.
For OUT endpoints:
This bit is set when the current bank is full, at the same time as RXOUTI.
