12.4.4 TX-Encoder
The TX-Encoder handles all kinds of data processing for data transmission via the
contactless interface. This includes character encoding, comprising parallel-serial
conversion, start- and stop bit generation, calculation and appending of parity bits, byte
adjustments for bit-oriented frames and encryption of the MIFARE products, and on the
other hand frame generation, which covers creation of start-of-frame, end-of-frame and
special protocol symbols as well as appending of CRC values.
