- Help
- "The Address Burst Management feature enables the Etherlink/MC 32 to
- relinquish control of the Micro Channel Bus at specific address boundary
- crossings. As an example, if the 16-byte boundary Address Burst
- Management is selected, the Bus Master relinquishes bus control as the
- address increments from xx0Fh to xx10h.
- In some system configurations, the Address Burst Management feature may
- provide improved performance, but generally it should be disabled."
