13.2.2.2. Pointer Register
Instead of passing huge data via the Mailbox, a Pointer register is introduced. The Pointer register contains the 32-bit address to the payload of the message. A payload could be the raw data to be passed to the receiving processor for further processing. However, a message could contain zero payload or data for processing. A write to the Pointer may not be necessary for a message passing.
This register is read-writeable via Avalon® -MM Agent (sender). However it is only readable by Avalon® -MM Agent (receiver) interface.
