measurement, the bulk or suspend current (190
碌A)
is delivered to the USB cable through PUR pin. The remaining 6

consumed by the device. As described in section 7.2.3 of USB 1.1 specification,
When computing suspend current, the current from VBus through
the pullup and pulldown resistors must be included.
