ADAS1000 CRC calculation

Hi, all.

I don't understand how to judge the received data is correct or not

by using frame CRC register.

 

<Question>

1. It is written in the datasheet category"CRC Word".

 

--------------------------------------------------------------------------------------

If data and checksum are received correctly,

the resulting CRC residue should equal the check constant

shown in Table 22.

--------------------------------------------------------------------------------------

Does "data" mean frame data excluding CRC WORD?

Does "checksum " mean Frame CRC register(0x41)?

 

 

2,What the kind of the calculation should host device do?

  Could you show me the calculation?

 

Thanks
