Core Configuration
Selects between custom and pre-defined standard configurations.
Table A-1 on page 33
defines the fixed parame-
ter values for different standard configurations.
RS Parameters
Wsymb
This parameter sets symbol width.
Fpoly
This parameter sets the decimal value of the field polynomial.
Table 2-1 on page 15
gives the default field polyno-
mial values for different symbol widths.
Gstart
This parameter sets the offset value of the generator polynomial. The starting value for the first root of the genera-
tor polynomial is calculated as rootspace * gstart.
