tion. Clearing this bit allows the SIE to continue token processing. This bit is set by the SIE when a Setup
Token is received allowing software to dequeue any pending packet transactions in the BDT before resum-
ing token processing. The PKT_DIS bit is set under certain conditions such as back to back SETUP
tokens. This bit is not set on every SETUP token and can be modified only when UCTRL.SUSPND = 0.

wake-up. For more information on RESUME signaling, see Section 7.1.7.5, 11.9 and 11.4.4 in the USB 1.1
specification.
