      0x0                22 & 23
      0xf                24

      0x0 preamp o/p -> V rail
      0x8 - 0xf no obvious difference

14.52 slow comparator 0x64 -> 0xa
      Ibias LF feedback  attachment
      0x8 (default)      25 27
      0xf                26 28

      0xf appears to reduce (but not eliminate) frequency and amplitude of saw tooth transients 
      no obvious effect on good event rate

      for nnaida13 combination of Ibias LF feedback 0x8 -> 0xf and slow comparator 0xa -> 0xf 
      largely eliminates saw tooth except for noisiest strips e.g. 1.1.W 'edge' strip
      good events 280k -> 61k
