LPC824 CRC CALC

Using LPC824 CRC engine :

Polynomial = x16 + x12 + x5 + 1   (ccitt)
Seed Value = 0xFFFF
Bit order reverse for data input: Yes
1's complement for data input: NO
Bit order reverse for CRC sum: Yes
1's complement for CRC sum: NO
CRC_MODE = 0x0000 0014
CRC_SEED = 0x0000 FFFF

 

For string  "ABC" result crc   0x10f0

Using another devices to calc with same parameters result  0x60d0  (ex. CRC calculation )

Any ideas please ?
