4 2 OUTPUT SIGNAL LEVELS
The following tables show the levels of the NS32FX100 output control signals during reset or power save mode
4 2 1 Freeze Mode Output Signals
4 2 2 Reset Power Restore Output Signals
Output signals are driven during Freeze mode (states S3
During state S6 of the Power Save mode output signals are
S4 S5) as follows
driven or floated either when reset is active or throughout

When MA1–15 CAS RAS0 and RAS1 are driven low their voltages
are below GND a 0 2V if less than 0 1 mA is driven
When refresh is enabled these signals are toggled When refresh is
s disabled these signals are driven low
