6.4.10.8 IPMC Reset Source Register
The IPMC Reset Source Register stores the source of the most recent reset. A one in the register
bit indicates that the associated reset has occurred. If more than one reset occurs from
different sources without clearing the corresponding register bits, one cannot determine the
most recent reset source since more than one bit will be set. The same situation will happen, if
two reset sources go active at the same time.
