The following tables give details on mode setting for the USB Serial Interface Engine (SIE) for both the control endpoint (EP0)
and non-control endpoint (EP1).
USB Mode Tables
Note:
3.
STALL bit is the bit 7 of the USB Non-Control Device Endpoint Mode registers. Refer to Section 14.3 for more explanation.
Mode Column:
The 'Mode' column contains the mnemonic names given to the modes of the endpoint. The mode of the endpoint is determined
by the 4 bit binaries in the 'Encoding' column as discussed below. The Status IN and Status OUT modes represent the status IN
or OUT stage of the control transfer.
Encoding Column:
The contents of the 'Encoding' column represent the Mode Bits [3:0] of the Endpoint Mode Registers (
Figure 14-2
and
Figure 14-
3
). The endpoint modes determine how the SIE responds to different tokens that the host sends to the endpoints. For example,
if the Mode Bits [3:0] of the Endpoint 0 Mode Register (
Figure 14-2
) are set to '0001', which is NAK IN/OUT mode as shown in
Table 20-1 above, the SIE of the part will send an ACK handshake in response to SETUP tokens and NAK any IN or OUT tokens.
For more information on the functionality of the Serial Interface Engine (SIE), see Section 13.0.
SETUP, IN, and OUT Columns:
Depending on the mode specified in the 'Encoding' column, the 'SETUP', 'IN', and 'OUT' columns contain the device SIE's
responses when the endpoint receives SETUP, IN, and OUT tokens respectively.
A 'Check' in the Out column means that upon receiving an OUT token the SIE checks to see whether the OUT is of zero length
and has a Data Toggle (Data1/0) of 1. If these conditions are true, the SIE responds with an ACK. If any of the above conditions
is not met, the SIE will respond with either a STALL or Ignore. Table 20-3 gives detailed analysis of all possible cases.
A 'TX Count' entry in the IN column means that the SIE will transmit the number of bytes specified in the Byte Count Bit [3:0] of
the Endpoint Count Register (
Figure 14-4
) in response to any IN token.

Comments
Ignore all USB traffic to this endpoint
On Control endpoint, after successfully sending an ACK
handshake to a SETUP packet, the SIE forces the
endpoint mode (from modes other than 0000) to 0001.
The mode is also changed by the SIE to 0001 from mode
1011 on issuance of ACK handshake to an OUT.
