Receive FIFO (READ) RFIFO (offset: 00…1F)
Received data stored in RFIFO (LSB is received first) can be organized in one of two
selectable ways (refer to figure 50):
– pure data up to a character length of 8 bits (incl. optional parity)
– additionally, one status byte per character with information about parity (if enabled)
and parity error.
Reading data from RFIFO can be done in 8-bit (byte) or 16-bit (word) access depending
on the selected bus interface mode. The LSB is received first from the serial interface.
