• T0: suspend_x output of UDC2 = “L”
• T1: Start of host resume (No timing specifications)
• T2: Resuming of clock supply from USB 2.0 PHY (Depends on the PHY specifications.)
• T3: End of host resume (more than 20 ms after T1)
Resume Operation by the Host
time
The host starts resume operation (“FS-K”) at arbitrary timing to wake up the device from
the suspend state. At this point, UDC2 sets suspend_x to “H”. (Even if the clock input to
UDC2 is stopped, suspend_x becomes “H”.) After checking that suspend_x = “H”, disable
the SuspendM (UTMI) input to PHY to resume the clock output from USB 2.0 PHY.
The host resume operation (“FS-K”) lasts for more than 20 ms, and completes after “SE0”.
UDC2 resumes operating at the same speed (HS/FS) as before the suspend state was
entered.
