Norm,

Here is the encoding of the slave register 1 bits
that we discussed:

  selection (bits 19-16):
    0 - chip 0 glue 0  
    1 - chip 0 glue 1  
    2 - chip 0 glue 2  
    3 - chip 0 glue 3  
    4 - chip 0 glue 4   
    5 - chip 0 glue 5  
    6 - chip 0 mpa  
    7 - chip 0 mpb
    8 - chip 1 mpa
    9 - chip 1 mpb
   10 - chip 0 interface data
   11 - chip 0 sync    
 bits 21-20:
    0 - disable
    1 - force to 1
    2 - force to 0
    3 - force pattern (single clock width pulse--done
        only when cam clock is running!)
 
                       Take care,
                       Doug
