MSB (IHIGHh): 20 = 14h
LSB (IHIGHl): 21 = 15h
Each LSB of IHIGHh represents 512µA and each LSB of IHIGHl represents 2µA. The sixteen bits threshold value
(IHIGHh;IHIGHl) is compared, bit to bit, to the sixteen bits value of the bias current reading (ILDh:ILDl). Warning bit Wx is set if
Reading > Threshold.

Each LSB of ILOWh represents 512µA and each LSB of ILOWl represents 2µA. The sixteen bits threshold value
(ILOWh;ILOWl) is compared, bit to bit, to the sixteen bits value of the bias current reading (ILDh:ILDl). Warning bit Wx is set if
Reading < Threshold.

Each LSB of TXHIGHh represents 25.6µW. This register is to be used in conjunction with TXHIGHl to yield a sixteen-bit value.
The values in TXHIGHh:TXHIGHl are in an unsigned binary format. The value in this register is uncalibrated. The sixteen bits
threshold value (TXHIGHh;TXHIGHl) is compared, bit to bit, to the sixteen bits value of the TX power reading (TXOPh:TXOPl).
Warning bit Wx is set if Reading > Threshold.

Each LSB of TXLOWh represents 25.6µW. This register is to be used in conjunction with TXLOWl to yield a sixteen-bit value.
The values in TXLOWh:TLOWl are in an unsigned binary format. The value in this register is uncalibrated. The sixteen bits
threshold value (TXLOWh;TXLOWl) is compared, bit to bit, to the sixteen bits value of the TX power reading (TXOPh:TXOPl).
Warning bit Wx is set if Reading < Threshold.
