3.2.4 COP Port (J6) Pin Assignments

The C2K includes an on-board 2 x 10-pin COP Port header (J6) for stepping through code at the
MPC7448 processor. The VDD_SENSE signal is fixed at +2.5V. Table 3-10 shows the COP Port
pin assignments.
NOTE: A jumper must be installed on the COP_EN header/jumper (P10) to enable the J6 inter-
face (see "COP_EN (P10)" on page 2-3).

* This pin may be pulled to ground by the COP adapter cable
to automatically enable the COP port instead of installing a
jumper on COP_EN header P10.

3.2.5 JTAG Port (J7) Pin Assignments

The C2K includes an onboard 2 x 5-socket JTAG header (J7) for FPGA programming and JTAG
Boundary Scan Chain.
