address accords with it, the UDC continues the process. If the address does not accord,
the UDC ignores this token.
The UDC can support a maximum of seven endpoints, excluding the control endpoint.
Tokens for endpoints that are not permitted are ignored.

asserted and the UDC informs FIFO that data transfer is completed. When
transmitting, following IN token, FIFO data is transferred. Finally, data CRC field is

transmitting, CRC is generated automatically and is transmitted. This function may be
compared by various transfer modes.

This field follows SYNC field in every USB packet. The UDC distinguishes the PID
The UDC uses this field to confirm whether or not this function was specified by the
If sub-channels of more than two is needed in fields of 4 bits, it decides the function.
A field of 11 bits is added by the host at each frame. This field follows the SOF token
This field is data of unit bytes in 0 to 1023. When receiving it, the UDC transfers
