Dear Aurix users,
I notice the register bit RSTCON2.CSS0 is always zero after power on reset.
The follwing description is from TC234 user manual
The RSTCON2.CSS bits indicate whether each CPU successfully flushed its write
buffers and reached an idle state before the previous reset. These bits can therefore be
used to determine whether RAM content integrity can be trusted after the previous reset
cycle.
It seems that the RAM did not successfully flush in our project.
I have no ideal that which process shoud I do to make RSTCON2.CSS0 is 1 after power on reset.
Thanks.

After power on reset, it should be Zero.
But for warm reset, it maybe '1' or '0'. We use '1' to judge CPU0 is in safe state.

Dear dw,
Thank you for your reply.
I triggerd the warm reset in my project, and the RSTCON2.CSS0 showed the value "1".
