ICC_CheckPresence()
The eIccId parameter is split into two fields: Card Detect Polarity and Card Slot number, by using the
most significant nibble and least significant nibble, respectively. Therefore, the most significant nibble of
the eIccId parameter is used to determine if the Card Detect Polarity is to be configured High or Low.
The constants CARD_DET_H and CARD_DET_L are defined in ICCMgt.h.
Examples:
1. If Card Detect Polarity is to be set to High when a card is inserted, it can be done so by calling:
2. If Card Detect Polarity is to be set to Low when a card is inserted, it can be done so by calling:
3. Calling ICC_Enable (eIccId, bIccATRAutoCheck, etc.) without OR’ing eIccId with CARD_DET_L or

Parameters
Return Codes AR_ICC_OK
Purpose
Synopsis
Parameters
Return Codes AR_ICC_OK
ICC_Enable( eIccId | CARD_DET_H, bIccATRAutoCheck,etc.).
ICC_Enable( eIccId | CARD_DET_L, bIccATRAutoCheck,etc.).
CARD_DET_H (in other words, eIccID <= 0x09) will default to CARD_DET_H.
eIccId: Input parameter
Specifies which Smart Card interface is to be activated. Possible values are:
AR_ICC_ERR_BAD_PARAM
Return the status of the specified ICC interface.
AR_ICC_RC ICC_CheckPresence ( IN enum ICC_ID eIccId );
eIccId: Input parameter.
The lower (least significant) 4-bits specify which Smart Card interface to activate.
Possible values are:
The higher (most significant) 4-bits specify whether the card detect polarity is high
(CARD_DET_H) or low (CARD_DET_L). See additional details at the end of the
description of this function.
