Byte addresses
MS byte (TXLOWh): 30 = 1Eh
LS byte (TXLOWl): 31 = 1Fh
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.

(RXHIGHh:RXHIGHl) is compared to the sixteen-bit value of the RX power result (RXOPh:RXOPl). WARN1 bit 7 is set if
Result > Threshold.

Each LSB of RXLOWh represents 25.6 μW, and each LS bit of RXLOWl represents 0.1 μW. The sixteen-bit threshold value
(RXLOWh:RXLOWl) is compared to the sixteen-bit value of the RX power result (RXOPh:RXOPl). WARN1 bit 6 is set if
Result < Threshold.

This register is provided for compliance with SFF-8472. It is implemented as general-purpose non-volatile memory. Read/write
access is possible whenever a valid OEM password has been entered. CHKSUM is read-only in User Mode.
