6.1.3

ULPI Interface Timing

The control and data timing relationships are given in Figure 6.3 and Table 6.2. The USB300 PHY

provides CLKOUT and all timing is relative to the rising clock edge. The timing relationships detailed

below apply to Synchronous Mode only.

Note:

VDD3.3 = 3.0 to 3.6V; VSS = 0V; TA = -40C to 85C; unless otherwise specified.

6.1.4

ULPI Register Array

The USB3300 PHY implements all of the ULPI registers detailed in the ULPI revision 1.1 specification.

The complete USB3300 ULPI register set is shown in Table 6.3. All registers are 8 bits. This table also

includes the default states of the register upon POR. The RESET bit in the Function Control Register

does not reset the bits of the ULPI register array. The Link should not read or write to any registers

not listed in this table.
