FUNCTIONAL DESCRIPTION
3-8 MPC505EVBUM/D
The coprocessor interface is a transparent, logical extension of the MC68332 MCU device
registers and instructions. To the external environment the CPU and coprocessor execution
model appear to be on the same chip.
A coprocessor interface is an execution model based on sequential instruction execution by the
CPU and coprocessor. For optimum performance, the coprocessor interface lets floating point
instructions execute concurrently with CPU integer instructions. Concurrent instruction
execution is further extended by the coprocessor, which executes multiple floating-point
instructions simultaneously.
3.6.2 Logic Analyzer Connectors
To debug hardware and software developed for the MC68331 MCU device, connect a logic
analyzer to the desired pins of PFB connectors P1 - P6.
