7FastResEn

0 : ResVoltFall debounce time = 4 ms

1 : ResVoltFall debounce time = 4 us

6SupResEn

RW_SS

0 : A reset is generated if VBAT or VSUP falls below

2.5V. If VBAT falls below ResVoltFall only an

interrupt is generated (if enabled) and the

uProcessor can shut down the system)

1 : A reset is generated if VBAT falls below

ResVoltFall or VSUP falls below vsup_min

5:3

ResVoltFall

RW_SM

This value determines the reset level ResVoltFall for

falling VBAT.

For stacked battery systems (ncells>0) the level

gets multiplied with the number of cells.

It is recommended to set this value at least 200mV

lower than ResVoltRise

0 : 2.5V * (ncells+1)

1 : 2.7V * (ncells+1)

2 : 2.95V * (ncells+1)

3 : 3.1V * (ncells+1)

4 : 3.2V * (ncells+1)

5 : 3.3V * (ncells+1)

6 : 3.4V * (ncells+1)

7 : 3.6V * (ncells+1)

2:0

ResVoltRise

RW_SM

This value determines the reset level ResVoltRise

for rising VBAT.

For stacked battery systems (ncells>0) the level

gets multiplied with the number of cells.

It is recommended to set this value at least 200mV

higher than ResVoltFall

0 : 2.5V * (ncells+1)

1 : 2.7V * (ncells+1)

2 : 2.95V * (ncells+1)

3 : 3.1V * (ncells+1)

4 : 3.2V * (ncells+1)

5 : 3.3V * (ncells+1)

6 : 3.4V * (ncells+1)

7 : 3.6V * (ncells+1)
