PIT registers are accessible only when the core is in supervisor mode. How to go to the supervisor mode?

Hello Zhang ,
Ok the RM is not clear. Ithink you could access in Normal mode.
SPC56 and MPC56 , weare using the same core e200z0

you can find some infos in e200z0RM.pdf (e200z0 Power Architecture)
in some cases, it is transparent.
Best regards
