MDRB—Memory Diagnostic Register B
Address
BB + 0000 19C0
Access
R/W
Memory Diagnostic Register B contains a 32-bit 64-byte aligned ad-
dress value that is directly compared to TLSB_ADR<37:6>, or an
address generated by the self-test address generator. The value
loaded into this register is used in conjunction with MDRA and
DDR0:3 to cause a specific data bit and/or check bit to be flipped
whenever a TLSB memory write address matches the value con-
tained in this register.
NOTE: Since the TLSB addresses are 64-byte aligned, only TLSB_ADR-
<37:6> need be compared with this register. TLSB_ADR<4:0> is not used
and TLSB_ADR<5> is the WRAP bit, which is ignored in the comparison.

Match Address. The register may be loaded
with an address value that is used in diagnostic
modes to cause correctable and uncorrectable
ECC errors to be written to memory at the 64-
byte aligned address contained in this field.
