A Message-Based Commander located at Logical Address 0, which
provides configuration management services such as address map
configuration, Commander and Servant mappings, and self-test and
diagnostic management.
A signal or interrupt generated by a device to notify another device of an
asynchronous event. Responses contain the information in the Response
register of a sender.
See Resource Manager.
Read-Modify-Write cycle; a bus cycle in which data from a single location
is read, modified, and then written back.
Release On Acknowledge; a type of VXI interrupter which always
deasserts its interrupt line in response to an IACK cycle on the VXIbus.
Release On Request; a type of VMEbus arbitration where the current
VMEbus master relinquishes control of the bus only when another bus
master requests the VMEbus.
seconds
A one-line, open collector, multiple-device handshake trigger protocol.
A device controlled by a Commander; there are Message-Based and
Register-Based Servants.
To place a binary cell into the 1 state (non-zero).
Any communication between Message-Based devices consisting of a write
to a Signal register. Sending a signal requires that the sending device have
VMEbus master capability.
A functional part of a MXI/VME/VXIbus device that detects data transfer
cycles initiated by a VMEbus master and responds to the transfers when
the address specifies one of the device's registers.
A device is in slave mode it if is responding to a bus cycle.
A device configured for installation in Slot 0 of a VXIbus
mainframe. This device is unique in the VXIbus system in that it
performs the VMEbus System Controller functions, including clock
sourcing, arbitration for data transfers across the backplane, and
MODID functions. Additional Slot 0 services include trigger
control. Installing such a device into any other slot can damage the
device, the VXIbus backplane, or both. The VXI-MXI can be
configured as either a Slot 0 device or a Non-Slot 0 device.
