Update interface timings. Clarify 4-bit data clocking. Clarify sending of RX CMD’s and interrupts. Introduce AutoResume feature. Route int pin to data(3) during 6-pin Serial Mode. Explain VBUS thresholds. Add T&MT diagram and updated text. Add new section to explain how PHY is aborted by Link. Various clarifications. 1.0rc2 January 13, 2004 Add block diagram. Tighten interface timing. Modify suspend protocol to more closely resemble UTMI. Add SPKR_L and SPKR_MIC to signal list and T&MT connector. Various clarifications. 1.0rc3 January 19, 2004 Specify that PHY must send RX CMD after Reset. Link + PHY clock startup time of no more than 5.6ms for a peripheral is now mandatory.
