CRC Driver API/interface file.
CRC programming sequence:
1. CRCChannelReset()
2. CRCInitialize()
3. CRCConfigure()
4. CRCEnableIntr() - if needed
5. Transfer data to PSA signature for generation of signature value
- DMA is utilized in Semi-CPU mode
- CPU need to pump data into PSA register in Full CPU mode.
6. CRCGetPSASectorSig()
- After complete transfer read CRC signature.
CRC signature generated depends on amount of data copied into
PSA register at a time/in single write. Though data pattern can be
8, 16, 32, or 64 bit, data copied into PSA register is always 64 bit
wide. If data pattern is less than 64 bit, then it is padded with
zeros to make it 64 bit write.
