S/W option identification.
Board revision code
Power-on reset by using JTAG (optional)
PCI cards Present Detect and card type
Local bus mode
Since part of the MPC8272ADSs’ modules are controlled by the BCSR and since they may
be disabled in favor of external hardware, the enable signals for these modules are
presented at the CPM expansion connectors, so that off- board hardware may be mutually
exclusive enabled with on-board modules.
