Description
When this bit is set, the SIE stalls an OUT packet if the Mode bits are set to ACK-OUT. The SIE stalls
an IN packet if the Mode bits are set to ACK-IN. This bit must be clear for all other modes.
When set, this bit causes an endpoint interrupt to be generated even when a transfer completes with
a NAK.
The ACK'ed transaction bit is set whenever the SIE engages in a transaction to the register's end-
point that completes with an ACK packet.
The mode controls how the USB SIE responds to traffic and how the USB SIE changes the mode of
that endpoint as a result of host packets to the endpoint.
