In a system without the availability of DMA controller, the CRC routine can be operated by CPU provided the CPU has enough throughput. CPU needs to read from the memory area from which CRC is to be performed.
A memory area with 2 Mbytes is to be checked with the help of the CPU. CRC operation is to be performed every 1 Kbyte. In CPU mode, the MCRC_CRC_REGL1/H1 is not updated and contains indeterminate data.
