SNOOZE AND RECOVERY CYCLE SWITCHING CHARACTERISTICS
Notes:
1. The assertion of ZZ allows the SRAM to enter a lower power state than when deselected within the time specified. Data
2. ADSC and ADSP must not be asserted for at least 2 cyc after leaving ZZ state.
3. Configuration signal MODE is static and must not change during normal operation.
4. Guaranteed but not 100% tested. This parameter is periodically sampled.
5. Tested with the load in Figure 2.
