STXDAT.6
Data to be transmitted to smart card. Gets stored in the TX FIFO and then extracted by
the hardware and sent to the selected smart card. When the MPU reads this register,
the byte pointer is changed to effectively “read out” the data. Thus, two reads will
always result in an “empty” FIFO condition. The contents of the FIFO registers are not
cleared, but will be overwritten by writes.
