Package
Pin # Signal
Type Checked Recommendations
FATAL_ERR# B40 90 O
YES
NO
UNKNOWN
Fatal Error Output
Used to signal fatal error condition to other devices,
or to light status LED, etc. If FATAL_ERR# is not
used, ok to leave this pin unconnected.

PU
YES
NO
UNKNOWN
Hot Plug PRSNT# Input
Active-low slot control logic input that connects to
the PCI Express slot’s PRSNT# signal, which is
typically grounded. See the data book for details.
If used, this pin should be externally pulled high to
VDD_IO. Otherwise, ok to leave unconnected.

Indicator Outputs for lanes 3:0 (4 Pins)
These signals can directly drive common-anode
LED modules (external current-limiting resistors
are required). Alternate function for each pin is
GPIOn. See the data book for details on use.
