Byte addresses
MS byte (VLOWh): 14 = 0Eh
LS byte (VLOWl): 15 = 0Fh
Each LS bit of VLOWh represents 25.6 mV and each LS bit of VLOWl represents 0.1 mV. The sixteen-bit threshold value
(VLOWh:VLOWl) is compared to the sixteen-bit value of the voltage result (VINh:VINl). WARN0 bit 4 is set if
Result < Threshold.

Each LS bit of IHIGHh represents 512 μA and each LS bit of IHIGHl represents 2 μA. The sixteen-bit threshold value
(IHIGHh:IHIGHl) is compared to the sixteen-bit value of the bias current result (ILDh:ILDl). WARN0 bit 3 is set if Result >
Threshold.

(ILOWh:ILOWl) is compared to the sixteen-bit value of the bias current result (ILDh:ILDl). WARN0 bit 2 is set if
Result < Threshold.

Each LS bit of TXHIGHh represents 25.6 μW, and each LS bit of TXHIGHl represents 0.1 μW. The sixteen-bit threshold value
(TXHIGHh:TXHIGHl) is compared to the sixteen-bit value of the TX power result (TXOPh:TXOPl).WARN0 bit 1 is set if Result >
Threshold.
