Description
NMI/GPIOS_0
I
CMOS_V3P3
1
20K, PD
V3P3S
NMI: This is an NMI event
indication to iLB. When
operating as NMI event
indication pin function
(selected via the NMI SMI
Event Native GPIO Enable soft
strap), the pin is a push-pull.
If the NMI interface is not
used, the signals can be used
as GPIO Port 0.
ERROR2_B/GPIOS_1
O
CMOS_V3P3
1
V3P3S
Root port error collector
output. The platform board
must ignore this SoC output
signal while PMU_PLTRST_B
(active-low SoC output) is
asserted.If the ERROR2_B
interface is not used, the
signals can be used as GPIO
Port 1.
ERROR1_B/GPIOS_2
O
CMOS_V3P3
1
V3P3S
Root port error collector
output. The platform board
must ignore this SoC output
signal while PMU_PLTRST_B
(active-low SoC output) is
asserted. If the ERROR1_B
interface is not used, the
signals can be used as GPIO
Port 2.
ERROR0_B/GPIOS_3
O
CMOS_V3P3
1
V3P3S
Root port error collector
output. The platform board
must ignore this SoC output
signal while PMU_PLTRST_B
(active-low SoC output) is
asserted. If the ERROR0_B
interface is not used, the
signals can be used as GPIO
Port 3.
IERR_B/GPIOS_4
O
CMOS_V3P3
1
V3P3S
Internal Error. Catastrophic
error. Requires immediate
system shut down. During
power-up, IERR_B is valid
after the PMU_PLTRST_B
(Platform Reset) signal is
deasserted by the SoC. Before
the Platform Reset is
deasserted, the signal may be
unstable and falsely signal an
internal error. If the IERR_B
interface is not used, the
signals can be used as GPIO
Port 4.
