DS1672 BLOCK DIAGRAM
Figure 1
ADDRESS MAP
The counter is accessed by reading or writing the first 4 bytes of the DS1672 (00h - 03h). The control
register and trickle charger are accessed by reading or writing the appropriate register bytes as illustrated
in Figure 2. If the master continues to send or request more data after the address pointer has reached
05h, the address pointer will wrap around to location 00h.

DATA RETENTION MODE
The device is fully accessible and data can be written and ready only when V
CC
is greater than V
PF
.
However, when V
CC
falls below V
PF
, (point at which write protection occurs) the internal clock registers
are blocked from any access. If V
PF
is less than V
BACKUP
, the device power is switched from V
CC
to
V
BACKUP
when V
CC
drops below V
PF
. If V
PF
is greater than V
BACKUP
, the device power is switched from
V
CC
to V
BACKUP
when V
CC
drops below V
BACKUP
. The registers are maintained from the V
BACKUP
source
until V
CC
is returned to nominal levels.
