| [in] | protocol | used to execute the command  | 
    | [in] | EnCRCRX | Enable CRC check over received data.  | 
    | [in] | EnCRCTX | Enable CRC over transmitted data.  | 
    | [in] | SendDataLen | Number of bytes to send.  | 
    | [in] | Timeout | Timeout in ms between sending the last bit to the card and receiving the first bit from the card.  | 
    | [in] | DSI | Divisor Send/Receive Integer (DSI/DRI) This parameter is mapped to the Divisor Send/Receive (DS/DI) value, which determines bit rate for sending data from PICC to PCD. The possible DS/DR values (mapped to the DSI/DRI index) are listed below.  | 
    | [in] | DRI | Divisor Send/Receive Integer (DSI/DRI) This parameter is mapped to the Divisor Send/Receive (DS/DI) value, which determines bit rate for sending data from PICC to PCD. The possible DS/DR values (mapped to the DSI/DRI index) are listed below.  | 
    | [in] | SendData | Data to transmit. Bits will always be transferred LSB first.  | 
    | [in] | SendData_len |  | 
    | [out] | RecvData | Returned data.  | 
    | [out] | RecvData_len |  | 
    | [in] | mempool | is used to store response data. Maybe NULL to use an internal mempool, in this case the data is only available until another command uses the internal mempool  |
