 On most boards, the Gateworks System Controller has the ability to disable primary board power. This is used as a form of 'hard reset' in many cases. You can determine if and why the board was hard reset by looking at the value of the GSC_RESET_CAUSE register.
 
 Note that the Newport boot firmware will display the reason on bootup. Note that the value of 0, reported as 'VIN' indicates the GSC did not reset the board power supply and the board powered up because of Vin being applied externally.
 
+Example:
+* Read register from Linux
+{{{#!bash
+i2cget -f -y 0 0x20 16
+}}}
+ The result of this register will be a hex value, consult register table for definition.  
+* Boot up of Newport
+{{{#!bash

+}}}
+ The value provided in the GSC banner above after "RST:" will be one of the following:
+ "VIN","PB","WDT","CPU","TEMP_L","TEMP_R","SLEEP","BOOT_WDT1","BOOT_WDT2","SOFT_PWR" consult [#GSC_RESET_CAUSERegisterR16:ResetCausethis table]
