• Bit 7 is the TIP bit. It indicates that the TIP board is installed and available for use.

• Bits 6-4 are 0 and reserved for future use.

• Bits 3-0 are the Board Configuration Bits. They identify a population

configuration (option) for the board. Each reference design has its own

configuration assignments. D0 and D2 are populated by R100 and R98

respectively (at location L-7) to set the board configuration at 0101 binary. See

Table 2-10 for the Am186CC microcontroller router reference design’s board

configuration bit assignments.
