iSystem iC5000 User Manual page 30

Typically there is no need to use the 'Force periodic Nexus SYNC' functionality unless a
specific application code is traced, which does not generate messages containing
absolute program counter information. As long as the user has no problems with the
trace use, it is recommended to keep the jumper J2 disconnected.
Jumper J2 was introduced with the debug adapter revision N1. Earlier versions don't
provide this jumper.
The following pinout is valid on the target side:

Blue colored signals are trace signals.
When connecting the BlueBox to the new embedded target for the first time, double
check that the debug adapter pinout matches with the target debug connector. Note
that a mismatch can result in a hardware failure.
38-pin Mictor MPC5xxx Nexus 16-bit Debug Adapter features resettable fuses on pins 9, 10, 11,
12, 15, 17, 19 and 21. These protect debug signals against overcurrent and cycle back to a
conductive state after the excessive current fades away. Signals on pins 1, 2, 3, 4, 5, 8, 13, 14,
16, 18, 20, 22, 23, 24, 26, 28, 30, 32, 34, 36 and 38 are protected via 47 ohm serial resistors.
The debug adapter connects to the target via a 38-pin Mictor connector, Tyco Electronics
5767055-1. A target should feature a matching part, for example Tyco Electronics 5767081-1 in
the SMT technology.
