LP-MSPM0G3507: what is different between MSPM0G3507 early and realese version?

Dear all,
I'm currently trying to find how to debeg on ealry MSPM0G3507

I already know as fallow:

- some register is changed even register address.

i hope to know what i have to be careful.

i have been reading the Technical Reference Manual (slau846.pdf)

In the TRM, it explains 'Pipelined Compare' on 1115~1118p 

it compares CC and PCC register but i have never found PCC register address.

i have comfused.

so, is there any document that explains what is changed between early and realesed version?

Any help is appreciated.

Kind regards,
