POD Hardware Reference
In-Circuit Emulation PODs
The following elements of interest are located on all
•emulation CPU - acts on behalf of target's CPU. On some PODs you must use the same CPU on the POD as it is used on the target (see your POD reference page). In such cases, remove the CPU from the POD and insert the CPU that you use in the target system, in its place.
•red LED (D3) - lit when CPU is running
•green LED (D4) - lit when Emulator is ready for emulation
•a connector, mostly marked ST3 - contains signal lines, some of which are hardware configuration lines (such as bank select signals), others you can use for signal generation (pattern generator outputs).
Here are some common signals found on the signal connector, commonly marked as ST3:
• | GND | Ground |
• | BPE | External breakpoint input. Active high. |
• | RESO/RO | Reset output. Connect to target to reset peripherals. |
• | TRES/TR | Target reset input. |
• | AUXn | AUX signal inputs (same as inputs on Emulator/trace) |
Note: On PODs that support synchronization between two or more Emulators (currently only the HC(S)12 Family, see the Synchronization section in the Hardware User's Guide for more information) AUX0 and AUX1 are cut short with Run/Stop synchronization line, and AUX2, AUX3 with RESET synchronization line. You should use these pins to connect to other PODs or target CPUs.

Note: The signal connector can also have other markings, like P1, U1, etc. Please refer to the
