The sample code below shows how a protected variable is defined and how its value can
be restored.
main() {
protected int state1, state2, state3;
...
_sysIsSoftReset(); // restore any protected variables
The bbram keyword may also be used instead if there is a need to store a variable in
battery-backed SRAM without affecting the performance of the application program. Data
integrity is not assured when a reset or power failure occurs during the update process.
Additional information on bbram and protected variables is available in the Dynamic C
User’s Manual.
