Communication Ports

Figure 1-3. The BDM_PORT Connector pin assignment

V1, V2, V3, and V4

The V1 – V4 options provide a way to use the alternate VFLS0 and VFLS1 BDM signals from the

MPC564. By default, the primary VFLS0 and VFLS1 signals are applied by V1 and V2 default

connections. To modify the BDM port to apply the alternate VFLS0 and VFLS1 signals, options

V1 and V2 should be cut and options V3 and V4 connected.

1.4.4.2 Nexus Connector

The 2001-Nexus standard defines several different standards for different speed accesses to a

microcontroller in a target system. These standards have been revised since that release. The new

connectors come in both a robust and a non-robust configuration. In addition, each connector has

2 definitions depending upon whether the connection is an Auxiliary only (Auxiliary In and

Auxiliary Out) connection or a JTAG IEEE 1149.1 port with an Auxiliary Output port.

NOTE

The MPC56x parts do not support the JTAG IEEE 1149.1 configuration.
