There is additional bit to this field. See next on the same table.
Table 5-9. BCSR2 Description (continued)
External Tools Identification. These lines, which are available at the CPM
expansion connectors, are intended to serve as tools' identifier. On-board
S/W may check these lines to detect The presence of various tools (h/w
expansions) at the CPM expansion connectors. For the external tools'
codes and their associated combinations see Table 5-12

Software Option (0:1). This field shows the state of a dedicated
dip-switches providing an option to manually change a program flow.
Un-implemented
Board Version Number (0:1). This field represents the version code,
hard-assigned to the MPC8272ADS. See Table 5-13, for version encoding.
Board Revision Number (0:1). This field represents the revision code,
hard-assigned to the MPC8272ADS. See Table 5-14, for revisions'
encoding.
Software Option 2. This is the LSB of the field. Shows the state of a
dedicated dip-switch providing an option to manually change a program
flow.
Flash Presence Detect(7:5). These lines are connected to the Flash SIMM
presence detect lines, which encode the Delay of Flash SIMM mounted on
the Flash SIMM socket. For the encoding of FLASH_PD(7:5) see
Table 5-10
Flash Presence Detect(4:1). These lines are connected to the Flash SIMM
presence detect lines which encode the type of Flash SIMM mounted on the
Flash SIMM socket. For the encoding of FLASH_PD(4:1) see Table 5-11
