initialized yet.
Power-on self configuration (POSC)
cannot execute because of problems
with system reset or because the
POSCEN switch is incorrectly
configured.
3FAILED,
TEST VXI interface is being initialized by
MITE power-on self configuration
(POSC) circuitry.
POSC has stalled.
4TEST POSC circuitry has initialized VXI
interface, setting PASSED and
DONE bits.
POSC stalled before clearing the

is ready to respond to Resource
Manager inquiries.
POSC completed successfully;
however, the Resource Manager
either hung or was not executed.
