IccLastByte should be set when it is time to switch to transmission mode and start the BGT timer. If it is not
immediately known when it is time to switch, call
To determine if all the expected bytes have been received, call ICC_RxLen(). Since the ICC_OK or
ICC_BREAK status occurs after reception of ICCLen bytes, this value should include any CRC/LRC
byte(s) received.

Parameters
Return the number of bytes received thus far.
unsigned Int ICC_RxLen ( void );
None.
Notify the SmartCard UART that all the expected bytes have been received. This
forces the switch to activation of block guard and wait times.
Void ICC_RxDone ( void );
None.
Deactivate the contacts of the selected SmartCard interface as specified by IccId.
The Vcc, RST, I/O and Clk signals are configured according to the ISO 7816-3
standard. This function uses the IccVCCOffDelay, as described in
before turning VCC off.
void ICC_Deactivate ( void );
None.
Enable or Disable PC (via DIRECT mode) or Application (via Bypass mode) to
directly control ICC I/O line.
ICC_RC ICC_Mode (
IccId : Input parameter
Specifies which SmartCard to allow direct access to I/O. Possible values are:
bEnable: Input parameter
If TRUE, it enables the selected mode.
bPC_DIRECT: Input parameter
Enables or disables PC_DIRECT mode (if TRUE) or BYPASS mode (if FALSE).
