Is there the difference between software reset and Power-on reset of MPC5675K?

Hi,

Is there the difference between software reset and Power-on reset of MPC5675K? I think that some registers can't be cleared after software reset but all of them are initialized after Power-on reset. Is it ture?

Can you give me some projects about this?

Thank you!

It depends which software reset. If

ME_MCTL[TARGET_MODE] = 0000b => functional reset

ME_MCTL[TARGET_MODE] = 1111b => desctructive reset

POR reset is detructive reset as well.

Chapter 46.4.1 Reset state machine describes differences between reset categories.
