Detailed Description

finds max sum of two adjacent samples

input: 5x 12 bits (les 12 premiers bits sortant du bypasslin) output: 12 bits

computes 4 sums of 2 strips and gives the max max limited by 0xfff

As in the firmware the computation is performed only on the even energy sum, so the oddEvenFlag (14th bit) is used to exclude the energy of the odd strips from the computation. D.Valsecchi.
