The abnormal output symbols from MOD submodule of TI6670

Hi TI Folks,

Recently, I use the MOD submodule of BCP in TI 6670 for scrambling and modulation. 

In my code, the input of MOD is 1 byte per bit, i.e. (0 -> 0x0, 1 -> 0x1),  the WORD 1 of MOD header is 0x00000038, i.e. 64QAM, uncompressed  hard modulation.

According to my comparison,  if the input bit group is 0x010101010101, the output 64QAM symbols will be equal to zero  or abnormal value. Otherwise, the output is correct.

Can the MOD submodule be used standalonely ? How to solve this problem?  My development environment is the EVM 6670 + CCS 5. 1

Thanks elijah lee
