* The reader will transmit the supplied bytes in pbtTx to the target (tag). It waits for the response and stores the received bytes in the pbtRx byte array. The parity bits are handled by the PN53X chip. The CRC can be generated automatically or handled manually. Using this function, frames can be communicated very fast via the NFC reader to the tag. Tests show that on average this way of communicating is much faster than using the regular driver/middle-ware (often supplied by manufacturers).
