Miscellaneous Signals
MCERR_B/GPIOS_5
O
CMOS_V3P3
1
V3P3S
Machine Check Error. Fatal
uncorrectable error. During
power-up, MCERR_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 a
machine check error. If the
MCERR_B interface is not
used, the signals can be used
as GPIO Port 5.
UART1_RXD/GPIOS_6
I
CMOS_V3P3
1
20K, PD
V3P3S
UART Port 1 Serial Data Input:
Serial data input from the
device pin to the receive port
for UART port 1. If the
UART1_RXD interface is not
used, the signals can be used
as GPIO Port 6.
UART1_TXD/GPIOS_7
O
CMOS_V3P3
1
V3P3S
UART Port 1 Serial Data
Output: Serial data output to
the communication
peripheral/modem or data set
for UART port 1. If the
UART1_TXD interface is not
used, the signals can be used
as GPIO Port 7.

V3P3S
Legacy SMBus Clock - Port 0.
External pull-up required. If
the SMB_CLK0 interface is not
used, the signal can be used
as GPIO Port 8.

V3P3S
Legacy SMBus Data - Port 0.
External pull-up required. If
the SMB_DATA0 interface is
not used, the signal can be
used as GPIO Port 9.

OD
1
20K, PU
EXT PU
V3P3S
Legacy SMBus Alert - Port 0.
External pull-up required. If
the SMBALRT_N0 interface is
not used, the signal can be
used as GPIO Port 10.
SMB_DATA1/GPIOS_11
I/O,

20K, PU
EXT PU
V3P3S
IOSF SMBus Data - Port 1.
External pull-up required. If
the SMB_DATA1 interface is
not used, the signal can be
used as GPIO Port 11.
SMB_CLK1/GPIOS_12/

V3P3S
IOSF SMBus Clock - Port 1.
External pull-up required. If
the SMB_CLK1 interface is not
used, the signal can be used
SPKR or can be used as GPIO
Port 12.
