Common triggering Functions for multiple SAR instances

General Description

This set of functions is for initialization and usage of SAR common settings and simultaneous triggering.

Functions
cy_en_sar_status_t	Cy_SAR_CommonInit (PASS_Type *base, const cy_stc_sar_common_config_t *trigConfig)
	Initialize common SAR configuration registers. More...

Function Documentation

Cy_SAR_CommonInit()

cy_en_sar_status_t Cy_SAR_CommonInit	(	PASS_Type *	base,
		const cy_stc_sar_common_config_t *	trigConfig
	)

Initialize common SAR configuration registers.

Parameters

base	Pointer to structure describing PASS registers.
trigConfig	Pointer to structure containing configuration data. See cy_stc_sar_common_config_t.

Returns

• CY_SAR_SUCCESS : initialization complete
• CY_SAR_BAD_PARAM : input pointers are null, initialization incomplete

Function Usage

    cy_en_sar_status_t status;

    const cy_stc_sar_common_config_t config =
    {
    /* .pwrUpDelay              */  0UL,                                    
    /* .scanCount               */  16UL,                                   
    /* .simultControl           */  CY_SAR_SAR0 | CY_SAR_SAR1,              
    /* .simultTrigSource        */  CY_SAR_SAR0,                            
    /* .simultTrigEvent         */  CY_SAR_SIMULT_TRIG_EVENT_EDGE,          
    /* .simultTrigSync          */  CY_SAR_SIMULT_TRIG_SYNC_SAR_CLOCK,      
    /* .simultSamplesPerTrigger */  CY_SAR_SIMULT_TRIG_SAMPLE_SCAN_CNT,     
    /* .simultEOSIntrSelect     */  CY_SAR_SIMULT_TRIG_INTR_EOS             
    };

    status = Cy_SAR_CommonInit(PASS, &config);

    if (CY_SAR_SUCCESS != status)
    {
        /* Insert error handling */
    }
