Typedefs
typedef _DCL_VOLATILE struct dcl_df11	DCL_DF11

Functions
_DCL_CODE_ACCESS void	DCL_resetDF11 (DCL_DF11 *df)
	Resets DF11 internal storage data with interrupt protection. More...
_DCL_CODE_ACCESS void	DCL_forceUpdateDF11 (DCL_DF11 *df)
	Loads DF11 tuning parameter from its SPS parameter without interrupt protection. More...
_DCL_CODE_ACCESS void	DCL_updateDF11NoCheck (DCL_DF11 *df)
	Loads DF11 tuning parameter from its SPS parameter with interrupt protection. More...
_DCL_CODE_ACCESS bool	DCL_updateDF11 (DCL_DF11 *df)

_DCL_CRIT_ACCESS float32_t	DCL_runDF11 (DCL_DF11 *df, float32_t ek)
	Executes a 1st order Direct Form 1 controller. More...
