Description
test output; used for test purposes only; this pin is not
connected during normal operation
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset (internal pull-up resistor)
Remark: During reset, ensure that all the input pins to the
ISP1161A1 are not toggling and are in their inactive states.
indicates to the HC software the Number of Downstream Ports
(NDP) present:
0 — select 1 downstream port
1 — select 2 downstream ports
only changes the value of the NDP field in the
HcRhDescriptorA register; both ports will always be enabled;

DMA master device to inform the ISP1161A1 of end of DMA
transfer; active level is programmable; see
digital ground
DC ‘suspend’ state indicator output; active HIGH
DC wake-up input; generates a remote wake-up from
‘suspend’ state (active HIGH); when not in use, this pin must
be connected to DGND via an external 10 kΩ resistor (internal
pull-down resistor)
GoodLink LED indicator output (open-drain, 8 mA); the LED is
default ON, blinks OFF upon USB traffic; to connect a LED
use a series resistor of 470 Ω (V

this pin must be connected to DGND via a 1 MΩ resistor
HC wake-up input; generates a remote wake-up from
‘suspend’ state (active HIGH); when not in use, this pin must
be connected to DGND via an external 10 kΩ resistor (internal
pull-down resistor)
programmable clock output (3 MHz to 48 MHz); default
12 MHz
HC ‘suspend’ state indicator output; active HIGH
crystal input; connected directly to a 6 MHz crystal; when
XTAL1 is connected to an external clock source, pin XTAL2
must be left open
