73S12xxF Software User Guide
The T=0 and T=1 protocols affect which guard and wait times to use. For protocols other than these, use
whichever protocol (either T=0 or T=1) best matches the timing requirements. If neither protocol
matches, then the application will need to bypass the Smart Card UART.

Return Codes None.
Purpose
Synopsis
Parameters
IccCE: Input parameter
Card Event parameter. The following settings are available as defined in
API_STRUCT_12.h. Set this variable according to the hardware design where either
interrupt 2 or interrupt 3 is used for an external card event detect.
Activate the contacts of the selected Smart Card, as specified by eIccId. The VCC,
RST, I/O and CLK signals are configured according to the ISO 7816-3 standard.

);
Struct {
} ICC_Activate_t;
Where ICC_VOLTAGE is defined as:
IccVcc: Input parameter
Voltage to apply when powering up this card.
IccVCCOffDelay: Input parameter
Number of ETUs to delay before shutting off the VCC. The default should be set to
3 ETUs. The maximum value is 15.
IccVCCTmr: Input parameter
Number of ETUs to wait for VCC to become stable. This time is calculated as:
timer * 30.5 µs using a 32768 Hz clock. A value of 0 will result in no timeout (as
opposed to zero time). The maximum value is 15.
IccResetDelay: Input parameter
Specifies the number of ETUs to keep RESET asserted after power has stabilized.
IccInitialWaitingTime: Input parameter
Specifies the maximum delay in ETUs between the leading edges of two
consecutive characters of the ATR response.
