5.4 USB Characteristics
Table 5.27 On-Chip USB Full-Speed Characteristics (DP and DM Pin Characteristics)
Conditions: VCC = AVCC0 = VREFH = VCC_USB = 3.0 to 3.6 V, VREFH0 = 3.0 V to AVCC0
VSS = AVSS0 = VREFL/VREFL0 = VSS_USB = 0 V
PCLK = 24 to 50 MHz
T_a = T_opr
High drive output is selected by the drive capacity control register.
