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 VCC is greater than VPF.
However, when VCC falls below V
PF, (point at which write protection occurs) the internal clock registers
are blocked from any access. If VPF is less than VBACKUP, the device power is switched from VCC to
VBACKUP when VCC drops below VPF. If VPF is greater than VBACKUP, the device power is switched from
VCC to VBACKUP when VCC drops below VBACKUP. The registers are maintained from the VBACKUP source
until VCC is returned to nominal levels.
