DS1321
FRESHNESS SEAL MODE
When the battery is first attached to the DS1321 without V
power applied, the device does not
CC
immediately provide battery-backup power on V
. Only after V
exceeds V
will the DS1321
CCO
CCI
CCTP
leave Freshness Seal Mode. This mode allows a battery to be attached during manufacturing but not used
until after the system has been activated for the first time. As a result, no battery energy is drained during
storage and shipping.
