BX400ii Interposer Board User’s Manual 7
Introduction
The same 400-pin system interface is still provided to allow connection to the target system. In
addition, a top side 240-pin connection is added for the Intel Mobile Pentium II Processor in mini-
cartridge. This processor, plus the BX400ii Interposer Board, provides compatible functionality
with the Pentium II processor Mobile Module.
The 30-pin debug port connector connects to the run control cable, or debug port, of the emulator
or logic analyzer. The 190-pin processor system bus connector connects directly to the emulator or
logic analyzer bus preprocessor. This connection allows for full bus trace and triggering. Contact
your emulator or logic analyzer vendor for specific tool capabilities. See Table 2 for a reference list
of vendors.
