4.11 Residue-Voltage Protection
When battery is replaced, device power (Vdd) is taken off but residue-voltage remains. The residue-voltage may trips
below Vdd minimum, but not to zero. This condition may cause a poor power on reset. Fig.16 and Fig.17 show how to build
the residue-voltage protection circuit.
