Overview

The Smart Card interface GPIO driver handles the GPIO and FTM/TPM peripheral for clock generation, which covers all necessary functions to control the ICC. These functions are ICC clock setup, ICC voltage turning on/off, activation/deactivation, and ICC reset sequences. This driver doesn't support the ICC pin short circuit protection and an emergency deactivation.

Macros
#define	SMARTCARD_ATR_DURATION_ADJUSTMENT (360u)
	Smart card define which specifies the adjustment number of clock cycles during which an ATR string has to be received.

#define	SMARTCARD_INIT_DELAY_CLOCK_CYCLES_ADJUSTMENT (4200u)
	Smart card define which specifies the adjustment number of clock cycles until an initial 'TS' character has to be received. More...

Functions
void	SMARTCARD_PHY_GPIO_GetDefaultConfig (smartcard_interface_config_t *config)
	Fills in the configuration structure with default values. More...

status_t	SMARTCARD_PHY_GPIO_Init (UART_Type base, smartcard_interface_config_t const config, uint32_t srcClock_Hz)
	Initializes a Smart card interface instance. More...

void	SMARTCARD_PHY_GPIO_Deinit (UART_Type base, smartcard_interface_config_t config)
	De-initializes a Smart card interface, stops the Smart card clock, and disables the VCC. More...

status_t	SMARTCARD_PHY_GPIO_Activate (UART_Type base, smartcard_context_t context, smartcard_reset_type_t resetType)
	Activates the Smart card IC. More...

status_t	SMARTCARD_PHY_GPIO_Deactivate (UART_Type base, smartcard_context_t context)
	De-activates the Smart card IC. More...

status_t	SMARTCARD_PHY_GPIO_Control (UART_Type base, smartcard_context_t context, smartcard_interface_control_t control, uint32_t param)
	Controls the Smart card interface IC. More...
