FUNCTION
FUNCTION
FUNCTION
If set to logic 1, the buffer of the selected end-point is full.
In the event of an output end-point, this bit is cleared by executing the Clear Buffer command, if
the buffer was not overwritten.
In the event of an input end-point, this bit is set by the Validate Buffer command.
If set to logic 1, the selected end-point is stalled.
If set to logic 1, the last received packet for the selected end-point was a set-up packet. The
value of this bit is updated after each successfully received packet (i.e. an ACKED package on
that particular end-point).
If set to logic 1, the previously received packet was overwritten by a set-up packet. The value of
this bit is cleared by the Select End-point command.
If set to logic 1, the device has sent a NAK. If the host sends an output packet to a filled output
buffer, the device returns a NAK. If the host sends an input token to an empty input buffer, the
device returns a NAK.
This bit is set when a NAK is sent and the Interrupt On Nak feature is enabled.
This bit is reset after the device has sent an ACK after an output packet or when the device has
seen an ACK after sending an input packet. It is only defined for the 2 physical control
end-points.
