IccATR_TimeoutEnabled: Input parameter
Specifies if the ATR timeout is enabled (TRUE) or disabled (FALSE).
IccATR_Timeout: Input parameter
Specifies the maximum delay in ETUs between the leading edge of the first character
and last character of the ATR response, if enabled.
IccTS_Timeout: Input parameter
Specifies the maximum delay in ETUs between the de-assertion of the RST signal
and the leading edge of the TS byte of the ATR.
pIccATR: Input parameter.
Pointer to the ICC_Rx_t structure.
Return Codes
ICC_OK
The SmartCard is present and active.
ICC_ACTIVATION_INCOMPLETE
The SmartCard is present, but its reset is still asserted.
ICC_ERR_OVERCURRENT or ICC_ERR_VCC_UNSTABLE
An attempt to activate the SmartCard caused an over current condition and it
has been deactivated.
ICC_ERR_REMOVED
The SmartCard is not present.
ICC_ERR_TIMEOUT
One of the maximum delays was exceeded forcing a timeout. Take appropriate
action.
ICC_ERR_BREAK
Data was always received with parity error, necessitating break signaling of the
Smart Card (T=0 protocol).
ICC_ERR_PARITY
A byte was received with an invalid parity.
ICC_RX_PENDING
Reception has started, but is not yet completed. This code is returned on either
a successful completion or a termination due to error.
ICC_RX_OVERRUN
An Rx overrun condition has occurred, resulting in the loss of at least one byte.
If the Smart Card was powered-down on entry, this function will perform a cold-reset.
If the Smart Card was powered-up on entry, this function will perform a warm-reset.
This function will return after reception of the TS byte or an error condition.
The ICC_t structure should be set up to expect the largest possible ATR response. Call
ICC_RxLen() to
determine the current total number of bytes received. Call ICC_RxDone() to complete ATR reception.
(Refer to ICC_Tx() or ICC_Rx() for the ICC_t structure definition)
ICC_Status()
Purpose Retrieve the presence and active status of all the Smart Cards.
Synopsis
void ICC_Status ( OUT int *pnIccPresent, OUT int *pnIccActive );
Parameters
pnIccPresent: Output parameter
Specifies which SmartCards are present, Bit[n] corresponding to ICC[n], Bit[1] being
mapped to the least significant bit.
PnIccActive: Output parameter
Specifies which SmartCards are active, Bit[n] corresponding to ICC[n].
Return Codes None.
