16.2.1.51 Offset B6h: DRAM_DED_R1 - DRAM Rank 1 DED Error Counter Register
Counter for DED errors occurring for rank 1. The functionality of this counter is as
described in Section 16.2.1.48, “Offset B0h: DRAM_SEC_R0 - DRAM Rank 0 SEC Error
Counter Register” but applies to DED errors. The bits in this register are sticky through
reset.

16.2.1.52 Offset C2h: THRESH_DED - DED Error Threshold Register
This register is the threshold compare value for DED errors. An Error Threshold Detect
is signaled via bit 3 of DRAM_FERR or DRAM_NERR (see Section 16.2.1.36, “Offset
80h: DRAM_FERR - DRAM First Error Register” and Section 16.2.1.37, “Offset 82h:
DRAM_NERR - DRAM Next Error Register”) if either of the DED event counters
DRAM_DED_R0 or DRAM_DED_R1 (see Section 16.2.1.49, “Offset B2h: DRAM_DED_R0
- DRAM Rank 0 DED Error Counter Register” or Section 16.2.1.51, “Offset B6h:
DRAM_DED_R1 - DRAM Rank 1 DED Error Counter Register”) exceeds the value
programmed into this register. The bits in this register are sticky through reset. The
RANKTHREX register preserves knowledge of threshold exceeded events for software
(see Section 16.2.1.56, “Offset DCh: RANKTHREX - Rank Error Threshold Exceeded
Register” on page 497).
