Full-speed USB single-chip host and device controller
Description
DC’s DMA acknowledge input 2; when not in use, this pin
must be connected to V
HC’s interrupt output; programmable level, edge triggered
and polarity; see
DC’s interrupt output; programmable level, edge triggered
and polarity; see
test output; this pin is used for test purposes only; leave
this pin open
reset input (Schmitt trigger); a LOW level produces an
asynchronous reset (internal pull-up resistor)
indicates to the Host Controller software the number of
downstream ports 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 ISP1161 of end of DMA
transfer; active level is programmable; see
digital ground
DC’s ‘suspend’ state indicator output; active HIGH
DC’s 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 k resistor
(internal pull-up resistor)
GoodLink LED indicator output (open-drain, 8 mA); the
LED is ON by default, blinks OFF upon USB traffic; to
connect an LED, use a series resistor of 470

DC’s USB upstream port V
use, this pin must be connected to DGND via a 1 M
resistor
HC’s 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 k resistor
(internal pull-up resistor)
programmable clock output (3 to 48 MHz); default 12 MHz
HC’s ‘suspend’ state indicator output; active HIGH
crystal input; connected directly to a 6 MHz crystal; when it
is connected to an external clock oscillator, leave
pin XTAL2 open
