Notes:
12. Initially F
=F
until a USB packet is received.
13. Wake-up time for Wake-up Adjust Bits cleared to 000b (minimum setting)
14. Tested at 200 pF.
15. Measured at cross-over point of differential data signals.
16. Non-USB Mode refers to driving the D
–
/SDATA and/or D+/SCLK pins with the Control Bits of the USB Status and Control Register, with Control Bit 2 HIGH.
17. Per the USB 2.0 Specification, Table 7.7, Note 10, the first transition from the Idle state is excluded.
