9 JTAG Interface
The MPC5200B CPU provides a JTAG interface for connecting to
debuggers, emulators and boundary scan. The JTAG interface signals
extend to the module's phyCORE-connector. Furthermore, there is an
on-board JTAG connector (X2) located at the edge of the module,
which has the standard COP-Interface pinout but uses a 2.0 mm pin
pitch instead of 2.54 mm. The connector is not populated on the
standard version of the phyCORE-MPC5200B. You can order a
specific debug version of the module (denoted by the –D part number
extension) or populate a 2*8-pin header connector at space X2. The
numbering scheme is depicted on the phyCORE-MPC5200B. The
pinout of the JTAG interface at X2 is described in the following table.
