Figure 18. CRC32 High 16 and Low 16

 

 
Reconstruction example: 
 
CRC32 part 1 Low Byte = 26 
CRC32 part 1 High Byte = 143 
CRC32 part 2 Low Byte = 55 
CRC32 part 2 High Byte = 182 
 
CRC32 high 16 = (143 << 8) | 26 = 36 634 
CRC32 low 16  = (182 << 8) | 55 = 46 647 
 
CRC32 = [(36 634 & 0xFFFF) << 16] | (46 647 & 0xFFFF) 
CRC32 = 2 400 845 824 | 46 647 
CRC32 = 2 400 892 471
