Figure 8.6 HS Detection Handshake Timing Behavior from Suspend
While in suspend state an SE0 is detected on the USB. HS
Handshake begins. D+ pull-up enabled, HS terminations
disabled, SUSPENDN negated.
First transition of CLKOUT. CLKOUT "Usable" (frequency
accurate to ±10%, duty cycle accurate to 50±5).
Device asserts Chirp K on the bus.
Device removes Chirp K from the bus. (1 ms minimum width)
and begins looking for host chirps.
CLK "Nominal" (CLKOUT is frequency accurate to ±500
ppm, duty cycle accurate to 50±5).
