Smart Card PHY EMVSIM Driver

Overview

The Smart Card interface EMVSIM driver handles the EMVSIM peripheral, which covers all necessary functions to control the ICC. These functions are ICC clock setup, ICC voltage turning on/off, ICC card detection, activation/deactivation, and ICC reset sequences. The EMVSIM peripheral covers all features of interface ICC chips.

Function Documentation

void SMARTCARD_PHY_EMVSIM_GetDefaultConfig

(

smartcard_interface_config_t *

config

)

Parameters

config

The user configuration structure of type smartcard_interface_config_t. Function fill in members: clockToResetDelay = 40000, vcc = kSmartcardVoltageClassB3_3V with default values.

status_t SMARTCARD_PHY_EMVSIM_Init	(	EMVSIM_Type *	base,
		const smartcard_interface_config_t *	config,
		uint32_t	srcClock_Hz
	)

Parameters

base	The SMARTCARD peripheral module base address.
config	The user configuration structure of type smartcard_interface_config_t. The user is responsible to fill out the members of this structure and to pass the pointer of this structure into this function or call SMARTCARD_PHY_EMVSIMInitUserConfigDefault to fill out structure with default values.
srcClock_Hz	SMARTCARD clock generation module source clock.

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.

void SMARTCARD_PHY_EMVSIM_Deinit	(	EMVSIM_Type *	base,
		const smartcard_interface_config_t *	config
	)

Stops SMARTCARD clock and disable VCC.

Parameters

base	Smartcard peripheral module base address.
config	SMARTCARD configuration structure.

status_t SMARTCARD_PHY_EMVSIM_Activate	(	EMVSIM_Type *	base,
		smartcard_context_t *	context,
		smartcard_reset_type_t	resetType
	)

Parameters

base	The EMVSIM peripheral base address.
context	A pointer to a SMARTCARD driver context structure.
resetType	type of reset to be performed, possible values = kSmartcardColdReset, kSmartcardWarmReset

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.

status_t SMARTCARD_PHY_EMVSIM_Deactivate	(	EMVSIM_Type *	base,
		smartcard_context_t *	context
	)

Parameters

base	The EMVSIM peripheral base address.
context	A pointer to a smartcard driver context structure.

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.

status_t SMARTCARD_PHY_EMVSIM_Control	(	EMVSIM_Type *	base,
		smartcard_context_t *	context,
		smartcard_interface_control_t	control,
		uint32_t	param
	)

Parameters

base	The EMVSIM peripheral base address.
context	A pointer to a SMARTCARD driver context structure.
control	A interface command type.
param	Integer value specific to control type

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.
