KB
of battery backup SRAM. This ensures that
you have a safe place to store
critical
data. You can now
write
software
applications
without being concerned that system
crashes
will erase criti-
cal
data from the
memory.
There is a BTRY LED in the front
panel of the UNO-3074 (Figure 2.14).
Please replace the lithium battery if
the
BTRY
LED is
activated.
