MPC5777C - Detailed explanations about performance monitors

Hello!

I need to monitor a list of hardware events in the MPC5777C and I am having some trouble in understanding clearly the purpose of each performance monitor listed in the e200z7 core reference manual. The descriptions are very short and, sometimes, not clear enough.

Is there any other document which give more detailed explanations about the events that the performance monitor counts, their applications, etc.

Best regards,

Matheus

There is presentation mentioning some changes between C90 (MPC56xx) and C55 (MPC57xx) implementation:

However MPC5777C (e200z759) uses older version of performance monitor as it is on predecessor devices.

There is an appnote related to e200z760:

Mainly I would point out e200z759 core RM:

I am afraid no further documents exists.
