1OVERVIEW
The xPC56XXMB Motherboard is an evaluation system supporting
Freescale’s MPC56xx microprocessors. The complete system consists of an
xPC56XXMB Motherboard and an xPC56xxADPT Mini-Module (not included)
which plugs into the motherboard. Different Mini-Modules are available for
evaluating the different devices in the MPC56xx family of microprocessors.
The evaluation system (Motherboard & Mini-Module) allows full access to the
CPU, all of the CPU’s I/O signals, and the motherboard peripherals (such as
CAN, SCI, LIN).
