AN4224 Trace support on MPC5744P for code coverage analysis

Dear all,

 

There are no Aurora pins available on the 144 pin package of MPC5744P.

When looking at Table-1 and Figure-1 in AN4224 does that mean that tracing through JTAG TAP (without using MDO pins) is not possible with MPC5744P in LQFP144?

For instance when someone wants to do code coverage analysis then the NPC Auxiliary Port has to be used on LQFP144 - which will be slower than Aurora or move to BGA257 where the high speed trace capabilities through Aurora is available. Is my assumption right?

 

Thanks
