Reserved. Reads as zero.
Manufacturing Mode Low. Tied to a center-
plane signal. Used by manufacturing to indicate
that the module is in a manufacturing environ-
ment.
TLSB CONWIN. Reflects the inverted state of
the TLSB_CONWIN L backplane signal.
TLSB BAD. Reflects the inverted state of the
TLSB_BAD L backplane signal.
TLSB Node ID. Identifies which node this module
is in a TLSB system.
CPU Number. Hardware responds with a 0 for
CPU0 and a 1 for CPU1.
