Default Value
0000 0000b = 00h (0mW)
Serial Address
A2h = 1010001b
Byte Address
28 = 1Ch
Each LSB represents 25.6
W. 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 value in TXHIGHh is
compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh.

Byte Address

Each LSB represents 0.1
W. This register is to be used in conjunction with TXHIGHh 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 value in TXHIGHh is
compared against TXOPh. Warning bit Wx is set if TXOPh > TXHIGHh. Since TXOPl 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
MIC3001 when doing threshold comparisons and setting alarm or warning b.
