Description
no connection; leave this pin open
HC DMA acknowledge input; when not in use, this pin must
be connected to V
this pin must be connected to V
resistor
HC interrupt output; programmable level, edge triggered
and polarity; see
no connection; leave this pin open
no connection; leave this pin open
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset (internal pull-up resistor)
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; see
(internal pull-up resistor)
DMA master device to inform the ISP1160 of end of DMA
transfer; active level is programmable; when not in use, this
pin must be connected to V
resistor; see
digital ground
no connection; leave this pin open
this pin must be connected to DGND via an external 10 k
resistor
no connection; leave this pin open
this pin must be connected to DGND via a 1 M resistor
HC wake-up input; generates a remote wake-up from the
suspend state (active HIGH); when not in use, this pin must
be connected to DGND via an external 10 k resistor
(internal pull-down resistor)
no connection; leave this pin open
HC suspend state indicator output; active HIGH
crystal input; connected directly to a 6 MHz crystal; when
this pin is connected to an external clock source,
pin XTAL2 must be left open
crystal output; connected directly to a 6 MHz crystal; when
pin XTAL1 is connected to an external clock source, this
pin must be left open
digital ground
power switching control output for downstream port 1;
open-drain output
