USB Mode Tables
Table 11. USB Register Mode Encoding
Mode
This lists the mnemonic given to the different modes that can be
set in the Endpoint Mode Register by writing to the lower nibble
(bits 0..3). The bit settings for different modes are covered in the
column marked “Mode Bits”. The Status IN and Status OUT
represent the Status stage in the IN or OUT transfer involving the
control endpoint.
Mode Bits
These column lists the encoding for different modes by setting
Bits[3..0] of the Endpoint Mode register. This modes represents
how the SIE responds to different tokens sent by the host to an
endpoint. For instance, if the mode bits are set to “0001” (NAK
IN/OUT), the SIE will respond with an
Refer to Section 17 for more information on the SIE functioning.
SETUP, IN, and OUT
These columns shows the SIE’s response to the host on
receiving a SETUP, IN and OUT token depending on the mode
set in the Endpoint Mode Register.
A “Check” on the OUT token column, implies that on receiving
an OUT token the SIE checks to see whether the OUT packet is
of zero length and has a Data Toggle (DTOG) set to ‘1.’ If the

DTOG bit is set and the received OUT Packet has zero length,
the OUT is ACKed to complete the transaction. If either of this
condition is not met the SIE will respond with a STALLL or just
ignore the transaction.
A “TX Count” entry in the IN column implies that the SIE transmit
the number of bytes specified in the Byte Count (bits 3..0 of the
Endpoint Count Register) to the host in response to the IN token
received.
A “TX0 Byte” entry in the IN column implies that the SIE transmit
a zero length byte packet in response to the IN token received
from the host.
An “Ignore” in any of the columns means that the device will not
send any handshake tokens (no ACK) to the host.
An “Accept” in any of the columns means that the device will
respond with an ACK to a valid SETUP transaction to the host.
Comments
Some Mode Bits are automatically changed by the SIE in
response to certain USB transactions. For example, if the Mode
Bits [3:0] are set to '1111' which is ACK IN-Status OUT mode as
shown in
[3:0] to NAK IN-Status OUT mode (1110) after ACK’ing a valid
status stage OUT token. The firmware needs to update the mode
for the SIE to respond appropriately. See
details on what modes will be changed by the SIE. A disabled
endpoint will remain disabled until changed by firmware, and all

11, the SIE will change the endpoint Mode Bits
