Function Documentation

Cy_AutAnalog_Init()

uint32_t Cy_AutAnalog_Init

(

const cy_stc_autanalog_t *

cfgAndStates

)

Initializes the entire Autonomous Analog with the configuration and states provided.

Parameters

cfgAndStates

The pointer to the structure containing the configuration data and the content of the State Transition Table for the entire Autonomous Analog.

Returns

The combined value of all the subsystem statuses, cy_en_autanalog_status_t.

Cy_AutAnalog_Disable()

void Cy_AutAnalog_Disable

(

void

)

Disables the Autonomous Analog and powers down the digital supply to reduce the leakage.

Note

The configuration of the Autonomous Analog in the MMIO, the content of the State Transition Table, data in the SAR ADC FIFO, and the DAC LUT will be lost.

Cy_AutAnalog_Enable()

void Cy_AutAnalog_Enable

(

void

)

Enable the Autonomous Analog for operation.

Note

This API does not start the Autonomous Controller, use Cy_AutAnalog_StartAutonomousControl for the actual start.

Cy_AutAnalog_LoadConfig()

uint32_t Cy_AutAnalog_LoadConfig

(

const cy_stc_autanalog_cfg_t *

analogCfg

)

Configures the Autonomous Analog per provided settings.

Note

This function also

• enables the IP block;
• configures individual initialization delays for enabled subsystems;
• loads trimming values for Autonomous Analog;

Parameters

analogCfg

The pointer to the structure containing configuration data for the entire Autonomous Analog.

Returns

The combined value of all the subsystem statuses, cy_en_autanalog_status_t.

Cy_AutAnalog_LoadStateTransitionTable()

cy_en_autanalog_status_t Cy_AutAnalog_LoadStateTransitionTable	(	uint8_t	numEntries,
		const cy_stc_autanalog_stt_t *	stateTransitionTable
	)

Configures the State Transition Table of the the Autonomous Controller per provided settings.

Parameters

numEntries	Number of entries in the State Transition Table.
stateTransitionTable	The pointer to an array containing configuration data for the entire State Transition Table.

Returns

The combined value of all the subsystem statuses, cy_en_autanalog_status_t.

Cy_AutAnalog_UpdateStateTransitionTable()

cy_en_autanalog_status_t Cy_AutAnalog_UpdateStateTransitionTable	(	uint8_t	numEntries,
		const cy_stc_autanalog_stt_t *	stateTransitionTable,
		uint8_t	startState
	)

Add or replace states in the State Transition Table.

Parameters

numEntries	The number of entries in the State Transition Table for add/replace.
stateTransitionTable	The pointer to an array containing a new set of configuration data for the State Transition Table, to be added or replaced.
startState	Defines the state in the State Transition Table from which the content update starts.

Returns

Combined value of all the subsystem statuses, cy_en_autanalog_status_t.

Cy_AutAnalog_PRB_LoadConfig()

cy_en_autanalog_status_t Cy_AutAnalog_PRB_LoadConfig	(	uint8_t	prbIdx,
		const cy_stc_autanalog_prb_t *	prbCfg
	)

Configures the PRB instance per settings in the configuration structure.

Parameters

prbIdx	Index of the PRB block within the Autonomous Analog infrastructure.
prbCfg	The pointer to a structure containing configuration data for the PRB subsystem.

Returns

The status of initialization, cy_en_autanalog_status_t.
