Purpose
Synopsis
Parameters
Return Codes None.
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.
ICC_Tx()
or
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.

void ICC_Status ( OUT int *pnIccPresent, OUT int *pnIccActive );
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].
ICC_Rx()
The SmartCard is present and active.
The SmartCard is present, but its reset is still asserted.
An attempt to activate the SmartCard caused an over current condition and it
has been deactivated.
The SmartCard is not present.
One of the maximum delays was exceeded forcing a timeout. Take appropriate
action.
Data was always received with parity error, necessitating break signaling of the
Smart Card (T=0 protocol).
A byte was received with an invalid parity.
Reception has started, but is not yet completed. This code is returned on either
a successful completion or a termination due to error.
An Rx overrun condition has occurred, resulting in the loss of at least one byte.
