int XSysMon_SetSeqChEnables	(	XSysMon *	InstancePtr,
		u64	ChEnableMask
	)

This function enables the specified channels in the ADC Channel Selection Sequencer Registers. The sequencer must be in the Safe Mode before writing to these registers.

Parameters:

	InstancePtr	is a pointer to the XSysMon instance.
	ChEnableMask	is the bit mask of all the channels to be enabled. Use XSM_SEQ_CH_* defined in xsysmon_hw.h to specify the Channel numbers. Bit masks of 1 will be enabled and bit mask of 0 will be disabled. The ChEnableMask is a 64 bit mask that is written to the three 16 bit ADC Channel Selection Sequencer Registers.

Returns:

• XST_SUCCESS if the given values were written successfully to the ADC Channel Selection Sequencer Registers.
• XST_FAILURE if the channel sequencer is enabled.

Note:

None.

int XSysMon_SetSeqInputMode	(	XSysMon *	InstancePtr,
		u32	InputModeChMask
	)

This function sets the Analog input mode for the specified channels in the ADC Channel Analog-Input Mode Sequencer Registers. The sequencer must be in the Safe Mode before writing to these registers.

Parameters:

	InstancePtr	is a pointer to the XSysMon instance.
	InputModeChMask	is the bit mask of all the channels for which the input mode is differential mode. Use XSM_SEQ_CH__* defined in xsysmon_hw.h to specify the channel numbers. Differential input mode will be set for bit masks of 1 and unipolar input mode for bit masks of 0. The InputModeChMask is a 32 bit mask that is written to the two 16 bit ADC Channel Analog-Input Mode Sequencer Registers.

Returns:

• XST_SUCCESS if the given values were written successfully to the ADC Channel Analog-Input Mode Sequencer Registers.
• XST_FAILURE if the channel sequencer is enabled.

Note:

None.

void XSysMon_SetSequencerEvent	(	XSysMon *	InstancePtr,
		int	IsEventMode
	)

The function enables the Event mode or Continuous mode in the sequencer mode.

Parameters:

	InstancePtr	is a pointer to the XSysMon instance.
	IsEventMode	is a boolean parameter that specifies continuous sampling (specify FALSE) or event driven sampling mode (specify TRUE) for the given channel.

Returns:

None.

Note:

The Event mode is only available in 7 Series XADC and Zynq. This API should be used only with 7 Series XADC and Zynq .

void XSysMon_SetSequencerMode	(	XSysMon *	InstancePtr,
		u8	SequencerMode
	)

This function sets the specified Channel Sequencer Mode in the Configuration Register 1 :

• Default safe mode (XSM_SEQ_MODE_SAFE)
• One pass through sequence (XSM_SEQ_MODE_ONEPASS)
• Continuous channel sequencing (XSM_SEQ_MODE_CONTINPASS)
• Single Channel/Sequencer off (XSM_SEQ_MODE_SINGCHAN)
• Simulataneous sampling mode (XSM_SEQ_MODE_SIMUL)
• Independent mode (XSM_SEQ_MODE_INDEPENDENT)

Parameters:

	InstancePtr	is a pointer to the XSysMon instance.
	SequencerMode	is the sequencer mode to be set. Use XSM_SEQ_MODE_* bits defined in xsysmon.h.

Returns:

None.

Note:

Only one of the modes can be enabled at a time.

int XSysMon_SetSingleChParams	(	XSysMon *	InstancePtr,
		u8	Channel,
		int	IncreaseAcqCycles,
		int	IsEventMode,
		int	IsDifferentialMode
	)

The function sets the given parameters in the Configuration Register 0 in the single channel mode.

Parameters:

	InstancePtr	is a pointer to the XSysMon instance.
	Channel	is the channel number for conversion. The valid channels are 0 to 5, 8, and 16 to 31. Channel 6 is valid for 7 series and Zynq XADC. Channel 32 to 35 are valid for Ultrascale.
	IncreaseAcqCycles	is a boolean parameter which specifies whether the Acquisition time for the external channels has to be increased to 10 ADCCLK cycles (specify TRUE) or remain at the default 4 ADCCLK cycles (specify FALSE). This parameter is only valid for the external channels.
	IsEventMode	is a boolean parameter that specifies continuous sampling (specify FALSE) or event driven sampling mode (specify TRUE) for the given channel.
	IsDifferentialMode	is a boolean parameter which specifies unipolar(specify FALSE) or differential mode (specify TRUE) for the analog inputs. The input mode is only valid for the external channels.

Returns:

• XST_SUCCESS if the given values were written successfully to the Configuration Register 0.
• XST_FAILURE if the channel sequencer is enabled or the input parameters are not valid for the selected channel.

Note:

• The number of samples for the averaging for all the channels is set by using the function XSysMon_SetAvg.
• The calibration of the device is done by doing a ADC conversion on the calibration channel(channel 8). The input parameters IncreaseAcqCycles, IsDifferentialMode and IsEventMode are not valid for this channel.

void XSysMon_SetTempWaitCycles	(	XSysMon *	InstancePtr,
		u16	WaitCycles
	)

This function sets the number of Wait Cycles for Temperature updation logic

Parameters:

InstancePtr

is a pointer to the XSysMon instance.

Returns:

None.

Note:

The default number of wait cycles are 1000(0x3E8).

void XSysMon_StartAdcConversion

(

XSysMon *

InstancePtr

)

This function starts the ADC conversion in the Single Channel event driven sampling mode. The EOC bit in Status Register will be set once the conversion is finished. Refer to the device specification for more details.

Parameters:

InstancePtr

is a pointer to the XSysMon instance.

Returns:

None.

Note:

The default state of the CONVST bit is a logic 0. The conversion is started when the CONVST bit is set to 1 from 0. This bit is cleared in this function so that the next conversion can be started by setting this bit.
