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
sequence of the next sent (IN endpoints) or received (OUT endpoints) packet.
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
interrupt (EPnINT), whatever the state of the Endpoint n Interrupt Enable bit (EPnINTE).
The user then has to acknowledge or to disable the interrupt source (e.g. RXOUTI) or to clear the EPDISHDMA bit (by writing a
one to the EPDISHDMAC bit) in order to complete the DMA transfer.
In ping-pong mode, if the interrupt is associated to a new system-bank packet (e.g. Bank1) and the current DMA transfer is
running on the previous packet (Bank0), then the previous-packet DMA transfer completes normally, but the new-packet DMA
transfer will not start (not requested).
If the interrupt is not associated to a new system-bank packet (NAKINI, NAKOUTI, etc.), then the request cancellation may
occur at any time and may immediately pause the current DMA transfer.
This may be used for example to identify erroneous packets, to prevent them from being transferred into a buffer, to complete a
DMA transfer by software after reception of a short packet, etc.
For control endpoints:
The FIFOCON and RWALL bits are irrelevant. The software shall therefore never use them on these endpoints. When read,
their value is always 0.
For IN endpoints:
This bit is set when the current bank is free, at the same time as TXINI.
