+            If enabled, firmware in flash including instructions and data will be moved into PSRAM on startup,
+            firmware code will execute directly from PSRAM.
+
+            With this option enabled, code that requires execution during an MSPI1 Flash operation
+            does not have to be placed in IRAM. Therefore codes that need to be executing during Flash
+            operations can continue working normally.
+
+            This feature is useful for high throughput peripheral involved applications to improve
+            the performance during MSPI1 flash operations.
