In case P1[6]/PON, P1[7]/CHARGE, VBAT3, P2[3]/ADC1 is input,
Iprotxxx_max = (Vext - 2.55)/(500+Rext)
Rext is an external resistor which is needed if the external voltage Vext exceeds the 2.8V.
(A lower protection current value of e.g. 100 uA is recommended in case power saving is important)
In case P1[6]/PON, P1[7]/CHARGE , P2[3]/ADC1 is output, Iprotxxx_max = (VDDIO - 2.55)/(500)
