RFIFOD
XFIFOD
location selected by an internal pointer which is automatically incremented after each
write access. This allows for the use of efficient “move string” type commands by the
processor.
Up to 32 bytes of transmit data can be written to the XFIFOD following an ISTAD:XPR
interrupt.

4.3.1
A read access to any address within the range 80h-9Fh gives access to the “current”
FIFO location selected by an internal pointer which is automatically incremented after
each read access. This allows for the use of efficient “moving string” type commands by
the processor.
The RFIFOD contains up to 32 bytes of received frame.
After an ISTAD:RPF interrupt, exactly 32 bytes are available.
After an ISTAD:RME interrupt, the number of bytes available can be obtained by reading
