Functional Description
2.16.9
VMEbus Requester
Bus requests are executed at bus request level 3. No other levels are available. The
requester uses the Release-On-Request (ROR) or Release-When-Done (RWD)
scheme. ROR should be preferred in single VMEbus master systems to increase the
transfer rate. Both register schemes are implemented as fair requester.
Settings are made in the MSTR – Master Control Register (0x0010) (read/write).
See Chapter 2.16.7 VMEbus Master Interface on page 58.
Unused daisy-chain lines are passed by (BG0IN#/OUT#, BG1IN#/OUT#, BG2IN#/
OUT#).
