I am using the HTRC110 IC for driving the antenna, and the responses are always controlled by the SCLK signal. But when I send the command to read the RFID response, the IC enters in a transparent mode and the frequency and codification of the signal changes... So, I would like to know if any of you knows this frequency and/or codification.
