Byte addresses
MS byte (VMINh): 10 = 0Ah
LS byte (VMINl): 11 = 0Bh
Each LS bit of VMINh represents 25.6 mV and each LS bit of VMINl represents 0.1 mV. The sixteen-bit threshold value
(VMINh:VMINl) is compared to the sixteen-bit value of the voltage result (VINh:VINl). ALARM0 bit 4 is set if Result < Threshold.

MS byte (IMAXh): 16 = 10h
LS byte (IMAXl): 17 = 11h
Each LS bit of IMAXh represents 512 μA and each LS bit of IMAXl represents 2 μA. The sixteen-bit threshold value
(IMAXh:IMAXl) is compared,to the sixteen-bit value of the bias current result (ILDh:ILDl). ALARM0 bit 3 is set if Result >
Threshold.

(IMINh:IMINl) is compared to the sixteen-bit value of the bias current result (ILDh:ILDl). ALARM0 bit 2 is set if
Result < Threshold.

Each LS bit of TXMAXh represents 25.6 μW, and each LS bit of TXMAXl represents 0.1 μW. The sixteen-bit threshold value
(TXMAXh:TXMAXl) is compared to the sixteen-bit value of the TX power result (TXOPh:TXOPl). ALARM0 bit 1 is set if Result >
Threshold.
