Notes:
1. These parameters are sampled but not 100% tested
2. In the ZZ mode, the SRAM will enter a low-power state. In this mode, data retention is guaranteed and the clock is active.
3. ADSC and ADSP should not be accessed for at least 100 nS after chip leaves ZZ mode.
4. Configuration signals
LBO
and
FT
are static and should not be changed during operation.
