CPU itself reads from the memory and write the data to the MCRC64_0_PSA_SIGREGL1/H1 inside MCRC Controller. When the first incoming data pattern arrives at the MCRC64_0_PSA_SIGREGL1/H1, the MCRC Controller will compress it. After n data patterns are compressed, CPU can read from the MCRC64_0_PSA_SIGREGL1/H1. It is up to the CPU on how to deal with the PSA signature value just read. It can compare it to a known signature value stored at another memory location.
