The footprint of X1 is designed for a double row 26-pin header with
2.0 mm pin spacing. The location of the odd pads on the top side of
the PCB is shown in Figure 10. The even pin numbers are located on
the bottom of the PCB. Pin header X1 is not installed on the standard
version of the phyCORE-MCF548x module. In addition, the BDM
signals are routed to pins on the Molex connectors (refer to Table 9).
The phyCORE-MCF548x Development Board (PCM-982) contains a
BDM signal converter circuitry through which decoded BDM signals
are routed to the connector at P3. This enables easy connection of the
phyCORE-MCF548x (mounted on a Development Board) to a host-
PC for start-up, download of user code and debugging.
Table 9 shows the pin assignment on the 26-pin BDM header X1.
