NOTE LS device mode is not allowed by a USB2.0 HS capable PHY, therefore it is not supported by TUSB1210. This is clearly stated in USB2.0 standard Chapter 7, page 119, second paragraph: “A high-speed capable upstream facing transceiver must not support low-speed signaling mode..” There is also some related commentary in Chapter 7.1.2.3. 5.3.1.1 TUSB1210 Modes vs ULPI Pin Status Table 5-1, Table 5-2, and Table 5-3 show the status of each of the 12 ULPI pins including input/output direction and whether output pins are driven to ‘0’ or to ‘1’, or pulled up/pulled down via internal pullup/pulldown resistors. Note that pullup/pulldown resistors are automatically replaced by driven ‘1’/’0’ levels respectively once internal IORST is released, with the exception of the pullup on STP which is maintained in all modes. Pin assignment changes in ULPI 3-pin serial mode, ULPI 6-pin serial mode, and UART mode. Unused pins are tied low in these modes as shown below. 16 Detailed Description Copyright © 2009–2015, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TUSB1210 |
