Reset Trigger ADR (Async DIMM Self-Refresh)
Upon system power loss, an ADR sequence will be triggered to allow ADR to flush the write-
protected data buffers in the memory controller and place the DRAM memory in self-
refresh mode. When this process is complete, the NVDIMM will then take control of the
DRAM memory and transfer the contents to the onboard Flash memory. After the transfer is
complete, the NVDIMM goes into a zero-power state. The data transferred will be retained
for the duration specified by the flash memory. The options are Enable and Disable .
