0</a> - turn debug logging off<br/></li>
    <li><b>frame=F</b> - Print raw frame parameters data for frame <b>F</b>. Valid values 0..7 and -1 (that will show function triggers instead of the parameter values). Frame 0 also hold "static" parameters - when written with "s" flags they only go there other parameters propagate to the future frames during frame interrupts.</li>
    <li><b>"gamma_structure</b> - show structure of the gamma tables cache. Gamma cache consists of 255 pages and index one, based on linked lists. It is designed to minimize floating point calcualions (made outside of the kernel) and facilitate scaling (integer) needed fro white balancing. So the "prototype" (non-scaled curves are cached in the top list with connected lists of scaled derivatives. For each table there are several sub-tables that can be requested (and cached after that) - reverse table (for histogram processing) and FPGA table (formatted to be written to the FPGA). Each gamma "type" is marked with a 16-bit hash, by default calculated as gamma value (in percents, 8 bits) and black level shift (fat zero), but it is possible to load arbitrary table and mark it with unique 16-bit hash16. When the curve is loaded it can be send to any of the 4 color channels with arbitrary 16-bit scale (0x400 is 1.0) by writing to one of GTAB_R, GTAB_G, GTAB_GB or GTAB_B registers (16 higher bits - hash16, lower 16 - scale, it is possible to change any set of bytes of the 32-bit word adding byte masks to the flags     ELPHEL_CONST_FRAMEPAIR_BYTE0, ELPHEL_CONST_FRAMEPAIR_BYTE1, ELPHEL_CONST_FRAMEPAIR_BYTE2, ELPHEL_CONST_FRAMEPAIR_BYTE3, ELPHEL_CONST_FRAMEPAIR_WORD0,FRAMEPAIR_WORD1.</li>
