     Note 20 celsius degree is not a totally correct number. This value may changes among chips.
 
+.. note::
+
+    The PSRAM requires a phase point calibration algorithm when operating at 120M. The phase point setting is related to the temperature at startup. When the temperature increases / decreases significantly during the operation of the chip, the PSRAM may experience read/write errors. To solve this problem, you can enable dynamic adjustment of the PSRAM phase point based on the temperature value with :ref:`CONFIG_SPIRAM_TIMING_TUNING_POINT_VIA_TEMPERATURE_SENSOR`. This creates a task that measures the temperature every :ref:`CONFIG_SPIRAM_TIMING_MEASURE_TEMPERATURE_INTERVAL_SECOND` seconds and adjusts the PSRAM phase point accordingly.

+
+    PSRAM 在 120M 运行时需要相位点校准算法。相位点设置与启动时的温度有关。当芯片运行期间温度大幅上升（下降）时，PSRAM 可能会出现读写错误。为解决这一问题，可以使能 :ref:`CONFIG_SPIRAM_TIMING_TUNING_POINT_VIA_TEMPERATURE_SENSOR`，根据温度值动态调整 PSRAM 相位点。这将创建一个任务，每隔 :ref:`CONFIG_SPIRAM_TIMING_MEASURE_TEMPERATURE_INTERVAL_SECOND` 秒测量一次温度，并相应调整 PSRAM 相位点。
