All ULPI signals use pad type pad_fsr. The following timing specifications assume a pad slew rate setting of 11 and a load of
50 pF.1

eSDHC timing specifications
This section describes the electrical information of the eSDHC.
All eSDHC signals use pad type pad_msr. The following timing specifications assume a pad slew rate setting of 11 and a load
of 50 pF.2
1.These timing parameters are specified assuming maximum operating frequency and the fastest pad slew rate setting
(11). When operating this interface at lower frequencies, increase the slew rate by using the 10, 01, or 00 setting to
increase edge rise and fall times, thus reducing EMI.
