The VMEbus system reset signal is
used to reset the VMEbus logic. It
causes the LRSTO_ signal to be
asserted which causes a local bus
reset.
The VMEbus system reset signal is
driven to reset the VMEbus.
The VMEbus system fail signal is
monitored by Tsi148’s interrupter
logic. If enabled, an interrupt is
generated on the falling edge of
SFAILI_.
The VMEbus system fail signal is
driven by Tsi148 when the
BDFAIL_ signal is asserted and the
SYSFAIL signal is not inhibited.
The VMEbus AC fail signal is
monitored by Tsi148’s interrupter
logic. If enabled, an interrupt is
generated on the falling edge of
ACFAILI_.
The system clock signal is driven
by Tsi148 when the system
controller function is enable.
These signals are connected to the
geographic address signals on the
VMEbus.
This signal is connected to the
geographic address parity signal on
the VMEbus.

This signal is 5 volt tolerant and
may be connected directly to the
VMEbus.
This signal is connected to the
VMEbus through an external
inverting open collector buffer.
This signal is 5 volt tolerant and
may be connected directly to the
VMEbus.
This signal is connected to the
VMEbus through an external
inverting open collector buffer.
This signal is 5 volt tolerant and
may be connected directly to the
VMEbus.
This signal is connected to the
VMEbus through an external
tri-state buffer.
Since these signals are either
grounded or open on the
backplane, they can be connected
directly to Tsi148.
Since this signal is either
