The following sections provide additional information pertaining to the
VME firmware settings of the MVME5500. A few VME settings are
controlled by hardware jumpers while the majority of the VME settings are
managed by the firmware command utility vmeCfg.
CR/CSR Settings
The firmware supports both Auto Slot ID and Geographical Addressing for
assigning the CR/CSR base address dependent on a hardware jumper
setting. See the VME64 Specification and the VME64 Extensions for
details. As a result, a 512K byte CR/CSR area can be accessed from the
VMEbus using the CR/CSR AM code.
