3.16.4.1 Appendix A System Power Management
*1) Reset: The operation of the DP/DM signals for initializing the USB device (hereafter called “the device”) from the
*2) Suspend: If no bus activity on the DP/DM lines including SOF is initiated by the host for 3 ms or longer, the device
*3) Resume: The operation of the DP/DM signals for resuming normal operation from the suspend mode. Resume
USB-Spec2.0 Device Controller Appendix
In USB, operations related to the enumeration and power control signals (DP/DM signals)
for reset and suspend from the host are also prescribed, in addition to normal transfer
operations. This Appendix provides information about the specifications of USB 2.0 PHY
to be connected and clock control on the system level required for processes related to the
DP/DM signals. For details of each process, please be sure to check the USB Specification
Revision 2.0, PHY Specification, and the UTMI Specification Version 1.05.
USB host (hereafter called “the host”). After reset, enumeration is performed and then normal transfer
operations such as Bulk transfers begin. Upon being connected, the device is always reset. The device
also needs to support reset operation at any other arbitrary timing. During the reset period, Chirp
operation is performed to determine whether the device operates in High-Speed (HS) or Full-Speed
(FS) mode.
needs to be put in the suspend mode to reduce power consumption. In this case, the device is required
to perform certain operations such as stopping the clock.
operation can be initiated either by the host or the device. Resume operation from the device is called
“remote wakeup”.
