asynchronous reset input; when reset is active, the internal
switch to the 1.5 k
external resistor is opened, and all pins
DPn and DMn are three-state; it is recommended that you
connect to V
BUS
through an RC circuit; refer to the schematics in
ISP1521 Hub Demo Board User’s Guide
analog or digital overcurrent detect selection input; a LOW
selects digital mode and a HIGH (3.3 Vor 5.0 V) selects analog
mode
