Dual band combiner PAP high pass filter output accumulation
threshold. The threshold is on the envelope of the signal
assuming the signal takes values is in the range [-1,1). The
threshold can be programmed in the range 0 to 512. The
threshold is interpreted as programmed_value/256. For
example, value of 256 implies the envelope threshold = 1.

In the interface rate or Tx input (IP) PA Protection high pass
filter module, when the high pass filter output average
exceeds a thershold error hit is generated. The PA protection
can be triggered when the number of such hits in a
programmable window exceeds the count threshold. The
moving average count threshold can be programmed in the
range 0 to 2^12-1. The error accumulation counter is
programmable with value in the range 1 to 2^12-1. The error
counter threshold is programmed in the register
