Functions
uint16_t	RESET_CauseGet (void)
	Returns the cause of previous reset.
void	RESET_CauseHandler (void)
	It handles the reset cause by clearing the cause register values. This is a weak attribute function. The user can override and implement the same function without weak attribute.
void	RESET_CauseClearAll (void)
	Clears the Reset Cause register.
static bool	RESET_CauseFromTrap (uint16_t resetCause)
	RESET cause from trap.
static bool	RESET_CauseFromIllegalOpcode (uint16_t resetCause)
	RESET cause from Illegal Opcode
static bool	RESET_CauseFromConfigurationMismatch (uint16_t resetCause)
	RESET cause from Configuration Mismatch
static bool	RESET_CauseFromExternal (uint16_t resetCause)
	RESET cause from External
static bool	RESET_CauseFromSoftware (uint16_t resetCause)
	RESET cause from Software
static bool	RESET_CauseFromWatchdogTimer (uint16_t resetCause)
	RESET cause from Watchdog Time
static void	RESET_CauseClear (enum RESET_MASKS resetFlagMask)
	RESET cause from Clear
