7.4.1 TUSB1210 Modes vs ULPI Pin Status

Table 7-1, Table 7-2, and Table 7-3 show the status of each of the 12 ULPI pins including input or output direction and whether output pins are driven to ‘0’ or to ‘1’, or pulled up or pulled down through the internal pullup or pulldown resistors.

Note that pullup or 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.
