In AUTO mode, MCRC Controller in conjunction with DMA controller can perform CRC without CPU intervention. A sustained transfer of data to both the PSA Signature Register (MCRC_PSA_SIGREGL1-4) and a CRC (Cyclic Redundancy Check) Value Register (MCRC_CRC_REGL1-4) are performed in the background of CPU. When a mismatch is detected, an interrupt is generated to the CPU. A 16-bit, current sector ID register (MCRC_CRC_CURSEC_REG1-4) is provided to identify which sector causes a CRC failure.
