Communication Ports

The MII connector location is for testing and the connection of an external Ethernet PHY device.

This connector is not installed or supported by the EVB application.

1.4.4 BDM and NEXUS Development Ports

Both NEXUS (MPC564 Readi Module) and standard BDM (background debug module)

development ports are provided on the MPC564EVB for application of integrated software debug

tool suites. In order to use the BDM, simply connect the 10-pin debug connector on the board,

BDM_PORT, to the P&E BDM wiggler cable provided in the kit. No special setting is needed.

Refer to the MPC564 User’s Manual BDM Section for additiona instructions. The NEXUS

interface provides the IEEE-ISTO 5001 50 pin standard I/O connections and connector and the

BDM port provides the standard 10 pin interface (refer to MPC564EVB schematic sheet 3 for

details). User should observe that both ports can not be applied at the same time. Note that the

NEXUS interface applies some of the MPC564 standard I/O signals from the MIOS module as

alternate development port I/O signals. Following are the I/O effected:

MGPIO 0, 1, 2, 3, 5, 6

MPWM 0, 1, 17, 19

IRQ0

NOTE:

BDM functionality and use is supported via third party developer

software tools. Details may be found on CD-ROM included in this

kit

1.4.4.1 BDM Port Options

The BDM Port provides several options for flexibility of operation.

JP3 - BDM Port Interface Level

JP3 provides the option of 2.6V or 3.3V interface levels on the BDM port. This allows the use of

legacy MPC555 BDM tools on the MPC564. The option is set for 3.3V interface from the factory.

The following JP3 reference is with the MPC564EVB setting with the COM ports facing left.

The signals which are neccessary for debug are available at connector (BDM_PORT). Figure 1-3

shows the (BDM_PORT) Connector pin assignment.
