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.
6.3.1 TUSB1210 Modes vs ULPI Pin Status
Table 6-3, Table 6-4, and Table 6-5 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.
