Bits 31:16 – CRCSEEDx[15:0] Polynomial SCD CRC Calculation Start Value bits

Bit 15 – CRCSELx Select CRC bit

ValueDescription
1 CRC polynomial(7:1) in CRCPOLYx
0 CRC bit length in CRCLENx will apply dedicated CRC polynomials.

Bits 14:8 – CRCLENx[6:0]CRCPOLYx[6:0] Polynomial Selection by Length for SCD CRC Check bit/Polynomial for SCD CRC Check bits

CRCLENx and CRCPOLYx share the same register location.
ValueDescription
When CRCLENx is selected:
0010000 CRC polynomial 0b1.1001.0000.1101.1001 = 0x190D9
0001000 CRC polynomial 0b1.0010.1111 = 0x12F
0000111 CRC polynomial 0b1000.1001 = 0x89
0000110 CRC polynomial 0b100.0011 = 0x43
0000101 CRC polynomial 0b10.0101 = 0x25
0000100 CRC polynomial 0b1.0011 = 0x13
0000011 CRC polynomial 0b1011 = 0xB
0000000 CRC for single cycle data not present, CRC verification deactivated, CRCSELx = 0b0.
When CRCPOLYx is selected:
11111111-0000001 CRC polynomial for single-cycle data
0000000 CRC polynomial 0x00 not applicable with CRCSELx = 0b1
