MS byte (IHIGHh): 20 = 14h
LS byte (IHIGHl): 21 = 15h
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.

Each LS bit of ILOWh represents 512 μA and each LS bit of ILOWl represents 2 μA. The sixteen-bit threshold value
(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.

Each LS bit of TXLOWh represents 25.6 μW, and each LS bit of TXLOWl represents 0.1 μW. The sixteen-bit threshold value
(TXLOWh:TXLOWl) is compared,to the sixteen-bit value of the TX power reading (TXOPh:TXOPl). ALARM0 bit 0 is set if
Result < Threshold.
