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 as shown in Table 18-1, 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. The firmware needs to update the mode for
the SIE to respond appropriately. See Table 18-1 for more details on what modes will be changed by the SIE. A disabled endpoint
will remain disabled until changed by firmware, and all endpoints reset to the disabled mode (0000). Firmware normally enables
the endpoint mode after a SetConfiguration request.
Any SETUP packet to an enabled endpoint with mode set to accept SETUPs will be changed by the SIE to 0001 (NAKing INs
and OUTs). Any mode set to accept a SETUP will send an ACK handshake to a valid SETUP token.
The control endpoint has three status bits for identifying the token type received (SETUP, IN, or OUT), but the endpoint must be
placed in the correct mode to function as such. Non-control endpoints should not be placed into modes that accept SETUPs.
Note that most modes that control transactions involving an ending ACK, are changed by the SIE to a corresponding mode which
NAKs subsequent packets following the ACK. Exceptions are modes 1010 and 1110
.

The response of the SIE can be summarized as follows:

Legend:
1. The SIE will only respond to valid transactions, and will ignore non-valid ones.
2. The SIE will generate an interrupt when a valid transaction is completed or when the FIFO is corrupted. FIFO corruption occurs
3. An incoming Data packet is valid if the count is < Endpoint Size + 2 (includes CRC) and passes all error checking;
4. An IN will be ignored by an OUT configured endpoint and visa versa.
5. The IN and OUT PID status is updated at the end of a transaction.
6. The SETUP PID status is updated at the beginning of the Data packet phase.
during an OUT or SETUP transaction to a valid internal address, that ends with a non-valid CRC.
