The following figure shows the location of the JTAG/Debug connector (P4).
Figure 10: JTAG/Debug Connector
Note: The COP interface is not available on revisions prior to Revision 1.2.
The JTAG/Debug connector provides the signals of the PowerQUICC II COP in-
terface port which allows easy connection of a Standard Motorola Third Party
COP-Interface Emulator. Additionally, it provides a second RS-232 interface for
debugging convenience (PowerQUICC II SMC1-interface) and the necessary sup-
ply voltages.
The COP-interface port can be used for:
• Program flow tracking
• Internal watch point and breakpoint generation
• Emulation system control over PowerQUICC II
The RXD/TXD pins of the PowerQUICC II SMC_1 are connected to the develop-
ment port as well as the debug mode connector (Pins 8 and 9) via RS-232 drivers.
Note: To enable the COP interface, SW1-4 must be set to ON position.
