Notes:
1. The assertion of ZZ allows the SRAM to enter a lower power state than when deselected within the time specified. Data
retention is guaranteed when ZZ is asserted and clock remains active.
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.
