This register is used to store data temporarily for the system software.
Each dava save register can hold the data of one general-purpose register.

The reason for the additional SAVE register for TLB refill exception processing is:
To address the case where a TLB refill exception is triggered during the processing of exceptions except the TLB refill exception.
