These general purpose pins may be used
either as inputs, edge sensitive interrupt inputs,
or outputs. When using internal ROM mode,
these pins have the following assignments:
GPIO1: USB SUSPEND Indicator; active high
GPIO2: Optional Serial EEPROM (93LC56
type) Chip Select
GPIO3: USB VBUS Detect Input (can be used
to force the IDE interface to high impedance
state)
GPIO4: Optional Serial EEPROM Data In/Out
GPIO5: ATA Drive Reset
GPIO6: A16 control line for external program
Flash memory when using firmware upgrade
capability (external ROM operation only)
GPIO7: Optional Serial EEPROM Clock output
This active low signal is used by the system to
reset the chip. The active low pulse should be
at least 100ns wide.
These signals are used for testing the chip.
User should normally leave them unconnected.
For board continuity testing, all pads (except
RBIAS, FSDP, USBDP, USBDM, FSDM,
RTERM, XTAL1, XTAL2, LOOPFLTR and
nTEST[0:2]) are included in an XNOR chain
which is enabled by pulling nTEST2 low. nIOR
is the output of the chain (the chain begins at
pin 2) and will reflect the toggling of a signal
on each pin. Circuit board continuity of the pin
solder connections after assembly can be
checked in this manner
