CRC 16 on FIFO data

[colin.gill]

Hi all, 

I'm having some difficulty adapting some code to generate a particular 16 bit crc. I have an expected result of: x0CA6 for a sample set of 32bit data (32 bit data x 64 to be precise). The datasheet specifies that the CRC should be initialized to 0xFFFF. 

I'm using some code that i found on here that takes a byte array as it's input and calculates a 16 crc. 

The polynomial is 0xD175.

I'd appreciate any help!
