CRC Algo for BMS L9963E Chip

[VP.6]

Hi Team

I am trying to communicate SPC574 with L9963E BMS IC

Can any one help in updating the CRC calculation for it

I tried some simple calculation with polynomial , but I dont see any response from the BMS IC

#define CRC_POLY (uint64_t)0x0000000000000033 /*CRC Poly:X^6 + X^4 + X^3 + 1*/

#define CRC_SEED (uint64_t)0x0000000000000038

I was able to build a test case against the "Special Frame" values.
