Device Settings

The XEM8320 supports the FrontPanel Device Settings in the table below, accessible from the FrontPanel Application as well as the Device Settings API.

XEM8320 Device Settings

The XEM8320 has six SYZYGY ports that support SmartVIO for automatic interface voltage selection.  These settings may optionally be overridden by the settings below.

We do not recommend manual override of these settings without careful consideration of the outcome.  Damage may be done to the XEM8320 and/or attached peripherals.

Note: All power-related device settings require a power cycle to take effect.

NAMETYPEDESCRIPTION
XEM8320_VIO1_VOLTAGEINT32VIO1 output voltage specified in 10’s of mV. For example, “180” would set VIO1 = 1.8v. Supported values: 0 (default), 100, 120, 150, 180.
XEM8320_VIO2_VOLTAGEINT32VIO2 output voltage specified in 10’s of mV. For example, “330” would set VIO2 = 3.3v. Supported values: 0 (default), 120, 150, 180, 250, 330.
XEM8320_VIO3_VOLTAGEINT32VIO3 output voltage specified in 10’s of mV. For example, “330” would set VIO3 = 3.3v. Supported values: 0 (default), 120, 150, 180, 250, 330.
XEM8320_SMARTVIO_MODEINT32Register used to control the behavior of the SmartVIO solver on the XEM8320. See SYZYGY Ports documentation for additional information on these modes.

0x00 – SmartVIO only (default)
0x01 – SmartVIO hybrid mode
0x02 – Device Settings only
XEM8320_FAN_MODEINT320=Binary mode (default)
1=Temperature slope mode (not supported at this time)
XEM8320_FAN_ENABLEINT32In binary mode, 0=disable, 1=enable (default)
In temperature slope mode, this setting is ignored.
XEM8320_FAN_TEMP_THRESHOLDINT32This setting is not supported at this time.

SYZYGY Device Discovery

The following settings are common to all FrontPanel devices that support SYZYGY either natively or through a compatible breakout board or reference platform.

The XEM8320 has six ports, supporting n=0..5.

NAMETYPEDESCRIPTION
SYZYGYn_PORT_STATUSINT32Indicates the selected voltage for this port in 10’s of mV.  For example, “330” means that the SmartVIO solution is 3.3V.  If a solution was not found, this will read “0” and the port will be unpowered.
