Firmware Settings
The following sections provide additional information pertaining to the
VME firmware settings of the MVME6100. 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 CR/CSR base address is initialized to the appropriate setting based on
the Geographical address; that is, the VME slot number. 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.
