Figure 49. USB OTG full speed timings: definition of data signal rise and fall time
USB high speed (HS) characteristics
Unless otherwise specified, the parameters given in Table 72 for ULPI are derived from
tests performed under the ambient temperature, fHCLK frequency summarized in Table 71
and VDD supply voltage conditions summarized in Table 70, with the following configuration:
output speed set to OSPEEDRy[1:0] = 11, unless otherwise specified
capacitive load C = 20 pF / 15 pF, unless otherwise specified
measurement points at CMOS levels: 0.5 VDD.
Refer to Section 5.3.20 for more details on the input/output characteristics.
