- Card 1HintThink of it as the brain's clock management.Memory TipRCC = Reset & Clock Control.
- Card 2HintLike a traffic cop for signals in a busy intersection.Memory TipNVIC = New Vectors for Interrupts.
- Card 3HintYour system's built-in stopwatch.Memory TipSYSTICK = System Timer for interrupts.
- Card 4HintIt's like hitting the refresh button.Memory TipSystem Reset = Reboot the system.
- Card 5HintConsider it a special reset for saved data.Memory TipBackup Reset = Backup memory clean-up.
- Card 6HintRelated to a backup domain action.Memory TipThink of 'B' in BDRST as Backup.
- Card 7HintThe pin responsible for primary power.Memory TipVDD sounds like 'Vee Dee Dee' - main source.
- Card 8HintInternal oscillator providing a basic clock option.Memory TipHSI is 'High Speed Internal' - quick and direct.
- Card 9HintExternal source providing precise clock control.Memory TipHSE stands for 'High Speed External' - think of external accuracy.
