Function Documentation

◆ Cy_HPPASS_SAR_Init()

cy_en_hppass_status_t Cy_HPPASS_SAR_Init ( const cy_stc_hppass_sar_t * sarCfg )

Loads the SAR ADC configuration.

Can be used after the Cy_HPPASS_Init function to update the SAR settings.

Note: If AC is running the initialization of SAR block is not allowed (CY_HPPASS_AC_INVALID_STATE will be returned).; If the SAR block is currently busy the initialization is not allowed (CY_HPPASS_SAR_INVALID_STATE will be returned).; Since the 'block ready' status is combined SAR and CSG, this particular SAR function cannot be protected from reinitialization during the 'block ready' == true condition, so it is on user's responsibility when and from where to call this function to reinitialize the SAR block.

Parameters

sarCfg Pointer to the SAR configuration structure cy_stc_hppass_sar_t. The pointer cannot be NULL.

Returns: Status of initialization, cy_en_hppass_status_t.

Used for FW control input connections of the muxed samplers.

Note: This function works only if cy_stc_hppass_sar_t::muxMode is set to CY_HPPASS_SAR_MUX_FW for selected mux. See TRM for details.

Parameters

muxMask The mask of AROUTE switch.

Function Usage

Cy_HPPASS_SAR_SetSwitch(sw);

◆ Cy_HPPASS_SAR_ClearSwitch()

__STATIC_INLINE void Cy_HPPASS_SAR_ClearSwitch ( uint16_t muxMask )

Clears selected AROUTE switch open.

Used for FW control input connections of the muxed samplers.

Note: This function works only if cy_stc_hppass_sar_t::muxMode is set to CY_HPPASS_SAR_MUX_FW for selected mux. See TRM for details.

Parameters

muxMask The mask of AROUTE switch.

Function Usage

Cy_HPPASS_SAR_ClearSwitch(sw);

◆ Cy_HPPASS_SAR_GetSwitchStatus()

__STATIC_INLINE uint16_t Cy_HPPASS_SAR_GetSwitchStatus ( void )

Reads the current state of the AROUTE switch.

Returns: Read back the current state of the associated switch control.

Function Usage

uint16_t sw = Cy_HPPASS_SAR_GetSwitchStatus();

◆ Cy_HPPASS_SAR_CountsTo_Volts()

float32_t Cy_HPPASS_SAR_CountsTo_Volts	(	uint8_t	chanIdx,
		uint16_t	vRef,
		int16_t	chanCounts
	)

Converts the raw ADC result in counts into the analog pin voltage in volts.

For example, for the 0.534-volt ADC, the return value is 0.534. Voltage calculation depends on ADC channel work modes: Averaging, Signed, Pseudo-Differential, and Sampler Gain.

The equation:

V = ((chanCounts + chanOffset * avgMultiplier) * vRef / 1000) / (4095 * avgMultiplier * samplerGain)

where,

chanCounts: the raw counts from the SAR 16-bit CHAN_RESULT register
avgMultiplier: the multiplier value based on Averaging mode (cy_stc_hppass_sar_chan_t) and the number of samples averaged (cy_en_hppass_sar_avg_t)
- CY_HPPASS_SAR_AVG_DISABLED : avgMultiplier is 1<<0
- CY_HPPASS_SAR_AVG_16 : avgMultiplier is 1<<4
chanOffset: the constant value based on Signed and Differential modes cy_stc_hppass_sar_chan_t
- for Signed mode - true and Differential mode - disabled, chanOffset is 2048
- for Signed mode - false and Differential mode - enabled, chanOffset is -2048
- for all other cases, chanOffset is 0
vRef: the SAR ADC reference voltage in millivolts (for example, 3300U).

Note: This function is valid only for the right-aligned result.

Parameters

chanIdx	The channel index . Valid range - 0..27.
vRef	The SAR ADC reference voltage in millivolts
chanCounts	Conversion result from Cy_HPPASS_SAR_Result_ChannelRead

Returns: The result in Volts.

Function Usage

◆ Cy_HPPASS_SAR_CountsTo_mVolts()

int16_t Cy_HPPASS_SAR_CountsTo_mVolts	(	uint8_t	chanIdx,
		uint16_t	vRef,
		int16_t	chanCounts
	)

Converts the raw ADC result in counts into the analog pin voltage in millivolts.

For example, for the 0.534-volts ADC, the return value is 534. Voltage calculation depends on ADC channel work modes: Averaging, Signed, Pseudo-Differential, and Sampler Gain.

The equation:

mV = ((chanCounts + chanOffset * avgMultiplier) * vRef) / (4095 * avgMultiplier * samplerGain)

where,

chanCounts: the raw counts from the SAR 16-bit CHAN_RESULT register
avgMultiplier: the multiplier value based on Averaging mode (cy_stc_hppass_sar_chan_t) and the number of samples averaged (cy_en_hppass_sar_avg_t)
- CY_HPPASS_SAR_AVG_DISABLED : avgMultiplier is 1<<0
- CY_HPPASS_SAR_AVG_16 : avgMultiplier is 1<<4
chanOffset: the constant value based on Signed and Differential modes cy_stc_hppass_sar_chan_t
- for Signed mode - true and Differential mode - disabled, chanOffset is 2048
- for Signed mode - false and Differential mode - enabled, chanOffset is -2048
- for all other cases, chanOffset is 0
vRef: the SAR ADC reference voltage in millivolts (for example, 3300U).

Note: This function is valid only for the right-aligned result.

Parameters

chanIdx	The channel index . Valid range - 0..27.
vRef	The SAR ADC reference voltage in millivolts
chanCounts	Conversion result from Cy_HPPASS_SAR_Result_ChannelRead

Returns: The result in millivolts.

Function Usage

◆ Cy_HPPASS_SAR_CountsTo_uVolts()

int32_t Cy_HPPASS_SAR_CountsTo_uVolts	(	uint8_t	chanIdx,
		uint16_t	vRef,
		int16_t	chanCounts
	)

Converts the raw ADC result in counts into the analog pin voltage in microvolts.

For example, for the 0.534-volts ADC, the return value is 534000. Voltage calculation depends on ADC channel work modes: Averaging, Signed, Pseudo-Differential, and Sampler Gain.

The equation:

uV = ((chanCounts + chanOffset * avgMultiplier) * vRef * 1000)/ (4095 * avgMultiplier * samplerGain)

where,

chanCounts: the raw counts from the SAR 16-bit CHAN_RESULT register
avgMultiplier: the multiplier value based on Averaging mode (cy_stc_hppass_sar_chan_t) and the number of samples averaged (cy_en_hppass_sar_avg_t)
- CY_HPPASS_SAR_AVG_DISABLED : avgMultiplier is 1<<0
- CY_HPPASS_SAR_AVG_16 : avgMultiplier is 1<<4
- CY_HPPASS_SAR_AVG_32 : avgMultiplier is 1<<4 in Signed mode and 1<<3 in Unsigned mode
chanOffset: the constant value based on Signed and Differential modes cy_stc_hppass_sar_chan_t
- for Signed mode - true and Differential mode - disabled, chanOffset is 2048
- for Signed mode - false and Differential mode - enabled, chanOffset is -2048
- for all other cases, chanOffset is 0
vRef: the SAR ADC reference voltage in millivolts (for example, 3300U).

Note: This function is valid only for the right-aligned result.
