suspend_x
• T0: End of bus activity
• T1: Recognition of suspend (3 ms after T0)
• T2: Remote wakeup start enable (5 ms after T0)
• T3: Transition to suspend state (10 ms after T0)
Suspend Operation in FS Mode
When the end of bus activity from the host (the end of packet) is detected, UDC2 starts
counting to recognize suspend.
When the “FS-J” is detected for more than 3 ms after T0, UDC2 recognizes suspend and
drives suspend_x “L”.
Resume operation from the device (remote wakeup) is enabled 5 ms after T0. For details,
refer to “4(2) Resume Operation by the Device (Remote Wakeup)”
The device must enter the suspend state no later than 10 ms after T0. Processes required
of the device system to enter the suspend state, such as stopping the clock supply from
USB 2.0 PHY, must be performed during this period.
