The maximum current the ISP1520 can sink on a pin is 8 mA.
Symbol names ending with underscore N (for example, NAME_N) represent active LOW signals.
Downstream ports 1 and 2 cannot be disabled.
To disable a downstream port n, connect both pins DPn and DMn to V
CC
(3.3 V); unused ports must
be disabled in reverse order starting from port 4.
