c. High-speed idle: The peripheral must detect a minimum of Chirp K-J-K-J-K-J. Each

asserting SE0 until the end of reset. If the host detects the peripheral Chirp K for
no less than 2.5 s, then no more than 100 s after the bus leaves the Chirp K
state, the host sends a TXCMD (NOPID) with an alternating sequence of Chirp Ks
and Js. Each Chirp K or Chirp J must last for no less than 40 s and no longer than
60 s.
Chirp K and Chirp J must be detected for at least 2.5 s. After seeing that
minimum sequence, the peripheral sets TERMSELECT = 0b and
OPMODE[1:0] = 00b. The peripheral is now in high-speed mode and sees !squelch
(01b on LINESTATE). When the peripheral sees squelch (10b on LINESTATE), it
knows that the host has completed chirp and waits for Hi-Speed USB traffic to
begin. After transmitting the chirp sequence, the host changes OPMODE[1:0] to
00b and begins sending USB packets.
