Error Rank Address (ERRRANK): Rank address of the address block of main
memory of which an error (single bit or multi-bit error) has occurred.
00 = rank 0 (DIMM0)
01 = rank 1 (DIMM0)
10 = rank 2 (DIMM1)
11 = rank 3 (DIMM1)

Multiple Bit Error Status (MERRSTS): This bit is set when an uncorrectable
multiple-bit error occurs on a memory read data transfer. When this bit is set,
the address that caused the error and the error syndrome are also logged and
they are locked until this bit is cleared. This bit is cleared when it receives an
indication that the processor has cleared the corresponding bit in the ERRSTS
register.

Correctable Error Status (CERRSTS): This bit is set when a correctable
single-bit error occurs on a memory read data transfer. When this bit is set, the
address that caused the error and the error syndrome are also logged and they
are locked to further single bit errors, until this bit is cleared. But, a multiple bit
error that occurs after this bit is set will over-write the address/error syndrome
info. This bit is cleared when it receives an indication that the processor has
cleared the corresponding bit in the ERRSTS register.

should be used when the Dynamic Powerdown bit is set. Else use the Sync value.
