Meaning
Lit whenever a write access is made to DRAM.
If not lit, either the CPU is executing entirely out
of the on-chip cache, or the CPU is halted.
Lit whenever the VME SYSFAIL line is
asserted.
Reflects the state of the PASS bit in the VXI
registers. Normally lit during the boot process
until the controller passes all of its self-tests. If it
remains lit, then PASS is 0 (zero), and the
controller has failed its self-test.
Lit when a VME access is made by this device
as a master.
Lit when another VME device accesses the
memory of this controller.
Lit when the SCSI port is busy.
Lit when the IDE disk is busy.
