The ''%%MS%%'' value sets the primary multiplier value (''%%PMV%%'') of the pixel processor's primary scalar. Its settings are as follow: | The ''<nowiki>MS</nowiki>'' value sets the primary multiplier value (''<nowiki>PMV</nowiki>'') of the pixel processor's primary scalar. Its settings are as follow: |
| |
| * If set to 00, it uses the value stored in the next part of the ''<nowiki>PIXC</nowiki>'' word: the Multiply Factor value. |
| * If set to 01, it uses the ''<nowiki>AMV</nowiki>'' (alternate multiplier value) coming from the decoder. |
| * If set to 10, it uses the bottom 3 bits of the color value from the decoder as the ''<nowiki>PMV</nowiki>'', and uses the top 2 bits of the color value from the decoder as the primary divider value (''<nowiki>PDV</nowiki>''). |
| * If set to 11, it uses the bottom 3 bits of the color value from the decoder as the ''<nowiki>PMV</nowiki>'' and does //not// set the ''<nowiki>PDV</nowiki>''. |
