 There are currently two places registers are saved, a non user accessible {{{FACTORY_DEFAULTS}}} section that is populated with the factory programmed register values, and a {{{USER_DEFAULTS}}} section that contains the current control register values when the user executes a {{{GSC_REG_BKP_SAVE}}} command via register [#GSC_REGISTER_BACKUP GSC_REGISTER_BACKUP (R31)] described above. From this register, a user can remotely load register defaults from either location. As an additional recovery measure, a {{{10x}}} press of the pushbutton will load the values stored in the {{{FACTORY_DEFAULTS}}} location and reset the GSC as well as powercycle the board.
 
+The factory default values are dependent upon the GSC firmware version that was programmed originally at the factory.
+
+When registers are restored from user/factory-default area only the following registers and bits are restored:
+ - R0[0:7]: GSC_CTRL_0
+ - R1[0:7]: GSC_CTRL_1
+ - R11[0:7]: GSC_INTERRUPT_ENABLE_0
+ - R15[0:2]: GSC_WRITE_PROTECT
+ - R17[0:7]: GSC_INTERRUPT_STATUS_1
+ - R18[0:7]: GSC_INTERRUPT_ENABLE_1
+ - R19[0:7]: GSC_THERMAL_PROTECT
+ - R20[0:7]: reserved
+ - R21[0:7]: GSC_BOOT_OPTIONS
+ - R22[0:7]: reserved
+ - R23[0:7]: CSC_CTRL_2
+ - R24[0:7]: reserved

+ - R28[0:7]: reserved
