19.3.1.2 Operation Timing Chart in Manual CRC Calculation Mode
Set the initial value of CRC calculation in the CRCRES register. If 8-bit data is written to the CRCDATA register, the
calculation result is stored in the CRCRES register on the next clock rising-edge. The CRC calculation result can be
checked anytime by reading the CRCRES register.
Figure 19-7 shows the operation timing of CRC calculation.
