23A.7.2 Hardware Standby Mode Timing
Figure 23A-4 shows an example of hardware standby mode timing.
When the STBY pin is driven low after the RES pin has been driven low, a transition is made to
hardware standby mode. Hardware standby mode is cleared by driving the STBY pin high, waiting
for the oscillation stabilization time, then changing the RES pin from low to high.
