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！
8 B. a8 [3 }- W! }+ t1 a
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
G(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
: Y4 u. ^. Q( H- I5 R( A式R(X)。以R(X)作为校验码。若用查表法，信息字、控制字基本码元的中间余式见
, c) k8 f  @0 C' P                 表1    中间余式表
信息字、控制字的码元  查表法中间佘式
01H  1110  0000B
02H  0111  0000B
04H  0011  1000B
08H  0001  1100B
l0H  0000  1110B
20H  0000  0111B
40H  1110  0011B
$ u& f' w' O! U, {/ c* n$ m- n( C' }80H  1001  0001B
  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）
