USB Mode Tables
Table 38. 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

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 tot he 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, the
SIE will change the endpoint Mode Bits [3:0] to NAK IN-Status
OUT mode (1110) after ACK’ing a valid status stage OUT token.
