Receive Header LINK Pointer Register
This Receive Header LINK Pointer Register indicates the starting address of the latest receive packet in the
RxHeaderArea. Since the buffer pointer is given in 8Quadlet unit, the lower order 5 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.
Receive ORB Data LINK Pointer Register
This Receive ORB Data LINK Pointer Register indicates the starting address of the latest receive ORB data in
the RxORBdataArea. 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.
