Notes: ISB measured with USB in suspend mode; using external square wave clock source (FOSC = 6MHz); transceiver pull-up
resistor of 1.5KΩ between V3.3 and D- and 15KΩ termination resistors on D+ and D- pins; no port pins sourcing current. The ISB
value is including power consumed by external resistors.
