15.5. CRC0 Bit Reverse Feature  
CRC0 includes hardware to reverse the bit order of each bit in a byte as shown in Figure 15.2. Each byte  
of data written to CRC0FLIP is read back bit reversed. For example, if 0xC0 is written to CRC0FLIP, the  
data read back is 0x03. Bit reversal is a useful mathematical function used in algorithms such as the FFT.

7:0 CRC0FLIP[7:0] CRC0 Bit Flip.  
Function  
Any byte written to CRC0FLIP is read back in a bit-reversed order, i.e. the written  
LSB becomes the MSB. For example:  
If 0xC0 is written to CRC0FLIP, the data read back will be 0x03.  
If 0x05 is written to CRC0FLIP, the data read back will be 0xA0.
