CRC32 Calculation in MPC5777C

const uint8_t TextString1[] = "0123456789"; 


CRC.CNTX[0].CRC_CFG.R = 0x00000005;        /* CRC-32 polynomial, Inversion selection enabled */
CRC.CNTX[0].CRC_CSTAT.R = 0xFFFFFFFF;   /* Seed value 0xFFFFFFFF */



for(i=0; i<sizeof(TextString1)-1; i++)                     /* size of TextString1 is decreased by 1 due to null character of string */
*(uint8_t*)&CRC.CNTX[0].CRC_INP.R = TextString1[i];

crc_outpt = CRC.CNTX[0].CRC_OUTP.R;




crc_outpt = 0x63e32165



But when i enter the same string on CRC32 Online calculator in following link

the result is a684c7c6



Why is this difference in output of CRC32?  Can you suggest any settings to be modified
