2.6 Single Property Modifiers


The following sections specify the valid Sprm values.

For ease of implementation, the Sprms are listed as 16-bit integers rather than structures. The following formulas specify the relationship between the 16-bit integer representation and the members of the Sprm structure. The single ampersand (&) represents the bitwise AND operation; all fractions are rounded down to the previous whole number.

Equation for ISPMD. ISPMD = SPRM AND 0x01FF

Equation for F Spec. Fspec = SPRM over 512 AND 0x0001

Equation for SGC. SGC = SPRM over 1024 AND 0x0007

Equation for SPRA. SPRA = SPRM over 8192
