PC8641 and PC8641D [Preliminary]
Figure 21-7. JTAG/COP Interface Connection for multiple PC8641 devices in daisy chain configuration
Notes:
1. Populate this with a 10
Ω resistor for short circuit/current-limiting protection.
2. KEY location; pin 14 is not physically present on the COP header.
3. Use a AND gate with sufficient drive strength to drive two inputs.
4. The COP port and target board should be able to independently assert HRESET and TRST to the processor in order to fully
control the processor as shown above.
5. This switch is included as a precaution for BSDL testing. The switch should be open during BSDL testing to avoid acciden-
tally asserting the TRST line. If BSDL testing is not being performed, this switch should be closed or removed.
6. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for improved signal
integrity.
