The TCR bits also allow for adequate fixed-rate refresh at three different temperature
thresholds (+15°C, +45°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 +35°C, the system can minimize self refresh current consumption by selecting the
+45°C setting. Using the +15°C setting in the same environment would result in an
inadequate refresh rate 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.
