Receive Stream Data LINK Pointer Register
This Receive Stream Data LINK Pointer Register indicates the starting address of the latest received stream data
in the RxStreamdataArea. Since the buffer pointer is in Quadlet unit, the lower order 2 bits are always “0”. Also,
since the buffer size is 2 Kbytes, the higher order 3 bits are always “0”.
Reading the higher order bytes holds the lower order bytes. Read the higher order bytes first, then the lower
order bytes.
Transmit Stream Data LINK Pointer Register
This Transmit Stream Data LINK Pointer Register indicates the starting address of unused area in the
RxStreamArea. Since the buffer pointer is in Quadlet unit, the lower order 2 bits are always “0”. Also, since
the buffer size is 2 Kbytes, the higher order 3 bits are always “0”.
Reading the higher order bytes holds the lower order bytes. Read the higher order bytes first, then the lower
order bytes. This register is read-only. Writing is ignored.
