关于CDT CRC校验的问题

sdwhlcf

我看规约里有个CRC校验表，那个表是如何得到的，我查了相关资料，有的人代码把那种校验码叫正码，谁能指点下，搞不定了？现在行业常用的都是反码，这个反码表我能计算出来！
. K5 o" W3 J3 B6 z
/ e! R' l- R, ]3 S1 |本规约采用CRC校验，控制字和信息字都是（n、k）=(48,40)  码组，生成多项式为
. y4 l! T$ |; T8 Q: m8 DG(X)=X8+X2+X+1,陪集码为FFH。按4.2条所述发码规则的顺序以 G(X)模2除前5个字节，生成余

  uint8 CRC8_Check_Table_XXX[256] = 这是正码表，和规约一致的，（正码表，不知是如何计算出来的，求方法）
