DPD operation disables all refresh-related activity. This mode will be used when the sys-
tem does not require the storage provided by the CellularRAM device. Any stored data
will become corrupted when DPD is enabled. When refresh activity has been re-enabled,
the CellularRAM device will require 150µs to perform an initialization procedure before
normal operation can resume. DPD should not be enabled using CR software access.
The TCR bits allow for adequate refresh at four different temperature thresholds: +15°C,
+45°C, +70°C, and +85°C. The setting selected must be for a temperature higher than the
case temperature of the CellularRAM device. If the case temperature is +50°C, the system
can minimize self refresh current consumption by selecting the +70°C setting. The +15°C
and +45°C settings would result in inadequate refreshing and cause data corruption.
The page mode operation bit determines whether page mode READ operations are
enabled. In the power-up default state, page mode is disabled.
