Default Value
0000 0000_b = 00_h (0mW)
Serial Address
A2_h = 1010001_b
Byte Address
32 = 20_h
Each LSB represents 25.6µW. This register is to be used in conjunction with RXMAXl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in RXMAXh is compared against RXOPh. Alarm bit Ax is set if RXOPh
> RXMAXh.

Default Value

Serial Address
A2_h = 1010001_b
Byte Address
33 = 21_h
Each LSB represents 0.1µW. This register is to be used in conjunction with RXMAXh to yield a sixteen-bit value. The
values in RXMAXh:RXMAXl are in an unsigned binary format. The value in this register is uncalibrated. The value in
RXMAXh is compared against RXOPh. Alarm bit Ax is set if RXOPh > RXMAXh. Since RXOPl is always zero, it is
recommended that this register always be programmed to zero. This register is provided for compliance with SFF-
8472. It is not used by the MIC3000 when doing threshold comparisons and setting alarm or warning bits.

Each LSB represents 25.6µW. This register is to be used in conjunction with RXMINl to yield a sixteen-bit value. The
value in this register is uncalibrated. The value in RXMINh is compared against RXOPh. Alarm bit Ax is set if RXOPh <
RXMINh.
