This mode enables auto sleep mode for automatic power savings and overwrites the application's control of sleep mode. When set to TRUE, the user-controlled sleep input is disabled. Instead, UltraRAM internally puts itself in and out of sleep mode to achieve automatic power savings. The criteria for UltraRAM to go in and out of sleep mode is a measure of inactive clock cycles determined by the AUTO_SLEEP_LATENCY attribute.

Note: The use of USE_EXT_CE_A/B is not permitted when in AUTO_SLEEP mode. Both attributes are not permitted to be true at the same time.
