Wake Up Bit/Chip Count Register (unit is bits; only exception is WU
Pattern Chip Mode, where unit is chips, see A_WUC.WUPMSEL)
Counter Register to define the maximum counts of bits/chips for Wake Up
detection.
Min: 00h = 0 Bits/Chips to count
In Random Bits or Equal Bits Mode this will cause a Wake Up
on Data Criterion immediately after Symbol Synchronization is found.
In Pattern Detection Mode this will cause no Wake Up on Data Criterion.
In this
Mode there is needed minimum 11h = 17 Bits/Chips to shift
one Pattern through the whole Pattern Detector. Because
comparision can only be started when at least the comparision
register is completely filled.
Max: 7Fh: 127 Bits/Chips to count after Symbol Sync found
