Token not issued.
Token is issued when "UACT=1" is written, and when
the FIFO buffer of the pipe is in Send/Receive
Enabled status. Token not issued when "UACT=0" or
the status is other than Send/Receive Enabled.
A token is issued when “UACT=1” is written,
regardless of the state of the FIFO buffer that
corresponds to the selected PIPE.
A token is not issued if “UACT=0”.
Token not issued
NAK response is sent to the token from the USB Host.
However, when "ATREPM=1", operations mentioned
in 2.17.5 are executed.
Does not respond to the token from the USB Host
Does not respond to the token from the USB Host
When an OUT token is sent from the USB Host, if the
FIFO buffer for the selected PIPE is in the
receive-enabled state, the data is received and an
ACK or NYET response is returned. If not, a NAK
response is returned.
When a PING token is sent from the USB Host, if the
FIFO buffer of the selected PIPE is in the
receive-enabled state, an ACK response is returned. If
not, a NAK response is returned.
For the Out-token from the USB Host, if the FIFO
buffer of the pipe is in Receive Enabled status, the
data is received and an ACK response is sent.
Otherwise the NAK response is sent.
If the corresponding FIFO buffer is in Send Possible
status, the data is sent for the token from the USB.
Otherwise a NAK response is sent.
For the Out-token from the USB Host, if the FIFO
buffer of the pipe is in Receive Enabled status, the
data is received. Otherwise, the data is deleted.
If the corresponding FIFO buffer is in Send Possible
status, the data is sent for the token from the USB.
Otherwise, a zero-length packet is sent.
A STALL response is sent to the token from the USB
Host.
Does not respond to the token from the USB Host.
