63 / 92 page  2009-2018 Microchip Technology Inc. DS00002646A-page 63 USB334x 7.0 ULPI REGISTER MAP 7.1 ULPI Register Array The USB334x PHY implements all of the ULPI registers detailed in the ULPI revision 1.1 specification. The complete USB334x ULPI register set is shown in Table 7-1. All registers are 8 bits. This table also includes the default state of each register upon POR or de-assertion of RESETB, as described in Section 5.6.2, "Power On Reset (POR)," on page 31. 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. The USB334x supports extended register access. The immediate register set (00-3Fh) can be accessed through either a immediate address or an extended register address.
