20.5.3
Figure 20.5 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.
20.5.4
Timing of Transition to Hardware Standby Mode:
1. To retain RAM contents with the RAME bit set to 1 in SYSCR
2. To retain RAM contents with the RAME bit cleared to 0 in SYSCR, or when RAM contents do

Drive the RES signal low at least 10 states before the STBY signal goes low, as shown in
figure 20.6. After STBY has gone low, RES has to wait for at least 0 ns before becoming high.
