Description
supply voltage (3.0 to 5.5 V)
voltage regulator ground supply
regulated supply voltage (3.3 V
±
10%) from internal
regulator; used to connect decoupling capacitor and pull-up
resistor on D
+
line;
Remark:
Cannot be used to supply external devices.

sensing input
GoodLink LED indicator output (open-drain, 8 mA); the LED
is default ON, blinks OFF upon USB traffic; to connect an
LED use a 330
series resistor;
wake-up input (edge triggered, LOW to HIGH); generates a
remote wake-up from ‘suspend’ state
‘suspend’ state indicator output (4 mA); used as power switch
control output (active LOW) for powered-off application or as
resume signal to the CPU (active HIGH) for powered-on
application
End-Of-Transfer input (programmable polarity, see
Table 23
);
used by the DMA controller to force the end of a DMA transfer
by the ISP1181
DMA request output (4 mA; programmable polarity, see
Table 23
); signals to the DMA controller that the ISP1181
wants to start a DMA transfer
DMA acknowledge input (programmable polarity, see
Table 23
); used by the DMA controller to signal the start of a
DMA transfer requested by the ISP1181
DMA write strobe input; used only in bus configuration
mode 1 (separate PIO and DMA ports)
DMA read strobe input; used only in bus configuration
mode 1 (separate PIO and DMA ports)
interrupt output; programmable polarity (active HIGH or LOW)
and signalling (level or pulse); see
Table 23
I/O ready output; a LOW level indicates that ISP1181 is
processing a previous command or data and is not ready for
the next PIO command or data transfer; a HIGH level signals
that ISP1181 will complete a PIO data transfer; applies only
to a PIO port or a PIO port shared with a DMA port
bus configuration selector; see
