Description
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
Grant on read, write or both.
0x0 = grant independent whether it is a read or write
0x1, 0x2, 0x3 = reserved
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
ID of the agent that is identified by this entry.
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
Number of valid entries in last round robin list #2
Programming any value > 8 will result in use of the full round-robin
list.
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
Number of valid entries in first round robin list #1
Programming any value > 16 will result in use of the full round-robin
list.
To ensure software backward compatibility, writes to unused or
reserved bits should be zero and reads must be ignored.
Number of valid entries in priority list
Programming any value > 16 will result in use of full priority list.
Number of valid entries in TDMA wheel
Programming any value > 128 will result in use of all 128 entries.
