	)

Activates the Smart card IC.

Parameters

base	The Smart card peripheral module base address.
context	A pointer to a Smart card 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.

SMARTCARD_PHY_Control()

status_t SMARTCARD_PHY_Control	(	void *	base,
		smartcard_context_t *	context,
		smartcard_interface_control_t	control,
		uint32_t	param
	)

Controls the Smart card interface IC.

Parameters

base	The Smart card peripheral module base address.
context	A pointer to a Smart card 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.

SMARTCARD_PHY_Deactivate()

status_t SMARTCARD_PHY_Deactivate	(	void *	base,
		smartcard_context_t *	context
	)

De-activates the Smart card IC.

Parameters

base	The Smart card peripheral module base address.
context	A pointer to a Smart card driver context structure.

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.

SMARTCARD_PHY_Deinit()

void SMARTCARD_PHY_Deinit	(	void *	base,
		smartcard_interface_config_t const *	config
	)

De-initializes a Smart card interface, stops the Smart card clock, and disables the VCC.

Parameters

base	The Smart card peripheral module base address.
config	The user configuration structure of type smartcard_interface_config_t.

SMARTCARD_PHY_GetDefaultConfig()

void SMARTCARD_PHY_GetDefaultConfig

(

smartcard_interface_config_t *

config

)

Fills in the configuration structure with default values.

Parameters

config

The Smart card user configuration structure which contains configuration structure of type smartcard_interface_config_t. Function fill in members: clockToResetDelay = 42000, vcc = kSmartcardVoltageClassB3_3V, with default values.

SMARTCARD_PHY_Init()

status_t SMARTCARD_PHY_Init	(	void *	base,
		smartcard_interface_config_t const *	config,
		uint32_t	srcClock_Hz
	)

Initializes a Smart card interface instance.

Parameters

base	The Smart card peripheral base address.
config	The user configuration structure of type smartcard_interface_config_t. Call the function SMARTCARD_PHY_GetDefaultConfig() to fill the configuration structure.
srcClock_Hz	Smart card clock generation module source clock.

Return values

kStatus_SMARTCARD_Success

or kStatus_SMARTCARD_OtherError in case of error.
