COP/JTAG Port
The common on-chip processor (COP) is part of the MPC8313E JTAG module and is implemented as a
set of additional instructions and logic. This port can connect to a dedicated emulator for extensive system
debugging. Several third-party emulators in the market can connect to the host computer through the
Ethernet port, USB port, parallel port, RS-232, and so on. A typical setup using a USB port emulator is
shown in
Figure 18
.

The 16-pin generic header connector carries the COP/JTAG signals and the additional signals for system
debugging. The pinout of this connector is shown in
Figure 19
