DESCRIPTION
I/O, X Daughterboard ID Code 2 signal. It is part of
the field that designates the type of
daughterboard connected.
I/O, X Reserved signal 13 in BCSR3.
I/O, X Daughterboard ID Code 4 signal. It is part of
the field that designates the type of
daughterboard connected.
I/O, L Chip In Socket signal. When this signal is
active (low), MPC8xxFADS logic notices that
the evaluated MPC821 resides in its socket. If
inactive, either the MPC821 is out of socket or
a daughterboard is not connected, in which
case the MPC8xxFADS becomes a
debugging station.
