A 'TX 0 Byte' entry in the IN column means that the SIE will transmit a zero byte packet in response to any IN sent to the endpoint.
Sending a 0 byte packet is to complete the status stage of a control transfer.
An 'Ignore' means that the device sends no handshake tokens.
An 'Accept' means that the SIE will respond with an ACK to a valid SETUP transaction.
Comments Column:
Some Mode Bits are automatically changed by the SIE in response to many 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 20-1
, the SIE will change the endpoint Mode Bits [3:0]
to NAK IN-Status OUT mode (1110) after ACKing a valid status stage OUT token. The firmware needs to update the mode for
the SIE to respond appropriately. See
Table 20-1
for more details on what modes will be changed by the SIE.
Any SETUP packet to an enabled endpoint with mode set to accept SETUPs will be changed by the SIE to 0001 (NAKing). Any
mode set to accept a SETUP will send an ACK handshake to a valid SETUP token.
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.
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 endpoint should not be placed into modes that accept SETUPs.
