MSB (VMINh): 10 = 0Ah
LSB (VMINl): 11 = 0Bh
Each LSB of VMINh represents 25.6mV and each LSB of VMINl represents 0.1mV. The sixteen bits threshold value
(VMINh;VMINl) is compared bit to bit to the sixteen bits value of the voltage reading (VINh;VINl). Alarm bit Ax is set if Reading
< Threshold.

MSB (IMAXh): 16 = 10h
LSB (IMAXl): 17 = 11h
Each LSB of IMAXh represents 512µA and each LSB of IMAXl represents 2µA. The sixteen bits threshold value (IMAXh;IMAXl)
is compared, bit to bit, to the sixteen bits value of the bias current reading (ILDh:ILDl). Alarm bit Ax is set if Reading >
Threshold.

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