Dear sir,
For the register: (EAh) LOGGED_FAULTS, base on documentation it could be clear after PMBus perform a Block_Write with 0 on it.
But after clear, UCD do not log faults any more even AC power cycle. Do you have any idea of this situation?
Here is our log shows each byte in EAh are all ZERO.

Thanks!
