VMEchip2 Board Status/Control Register
This register is the VMEchip2 board status/control register.
SYSFL This bit is set when the VMEchip2 is driving the
SYSFAIL signal.
SCON This bit is set if the VMEchip2 is system controller.
BF When this bit is high, the Board Fail signal is active.
When this bit is low, the Board Fail signal is inactive.
When this bit is set, the VMEchip2 drives SYSFAIL if the
inhibit SYSFAIL bit is not set.
ISF When this bit is set, the VMEchip2 is prevented from
driving the VMEbus SYSFAIL signal line. When this bit
is cleared, the VMEchip2 is allowed to drive the VMEbus
SYSFAIL signal line.
RST This bit allows a VMEbus master to reset the local bus.
Refer to the note on local reset in the GCSR Programming
Model section, earlier in this chapter. When this bit is set,
a local bus reset is generated. This bit is cleared by the
local bus reset.
