Internal DRAM to PMWB Parity Error Detected:
0 = Parity error not detected.
1= Parity error detected when a cacheline read from DRAM
was written to the PMWB as part of a Read/Modify/Write
operation (partial write). (NON-FATAL)
Internal System Bus or I/O to PMWB Parity Error
Detected:
0 = Parity error not detected.
1 = Parity error detected on a line write to PMWB. (NON-
FATAL)
Internal PMWB to System Bus Parity Error Detected:
0 = Parity error not detected.
1 = Parity error detected on data to the System Bus.
(NON-FATAL)
Internal PMWB to DRAM Parity Error Detected:
0 = Parity error not detected.
1 = Parity error detected when PMWB is flushed to DRAM.
