DebouncePDEnable: Input parameter
The higher order (most significant) nibble of this byte enables (SC_DEBOUNCEON)
or disables (SC_DEBOUNCEOFF) card debounce. The low order (least significant)
nibble of this byte enables (TRUE) or disables (FALSE) the Pull-Down.
Return Codes
AR_ICC_OK Successful operation.
ICC_Configure()
Purpose Get / Set the configurable protocol parameters of the specified Smart Card interface.
This function was developed to support different conformance tests. This API should
be called prior to calling ICC_Enable. It is the same as ICC_Configure_Ext, above,
with default values for IccHz (ICC_3600KHZ), DebouncePUEnable =
SC_DEBOUNCEON | TRUE, and DebouncePDEnable = SC_DEBOUNCEOFF | FALSE.

ICC_I2C1 0x42,
ICC_I2C2 0x44,
…
ICC_I2C7 0x4E; (Last external slot)
IccCE: Input parameter
Specifies the assignment of the INT2/INT3 pins for card events. Possible values are:
ICC_INT2_NONE 0x00,
ICC_INT2_I2C
0x01,
ICC_INT3_I2C 0x02;
bIccSetOperation: Input parameter
Specifies if the function is called to perform a Set operation (TRUE) or a Get
operation (FALSE).
